In the following months, energy commodity costs rose further markedly, reaching peaks in the Amsterdam spot mark<span class=\"_ _0\"></span>et of over 300 euros per MWh at the end of August. Since September<span class=\"_ _0\"></span>, and more markedly since December 2022, the price of natural gas has fallen significantly to below 80 euros per MWh for the first time in nine months. The downward trend continued in the first weeks of 2023.At the same time, since the beginning of 2022, global economic activity has shown signs of slowing down and inflation has risen almost every<span class=\"_ _4\"></span>where, continuing to reflect the increases recorded in energy prices and the consequent growth in food prices; in Italy in particular<span class=\"_ _0\"></span>, on average, consumer prices rose by more than 8% in 2022 (compared to a growth of +1.9% in 2021). During the same period in the Eurozone and the US, inflation was above 9% and 6%, respectively.In order to cope with the significant inflationary phenomenon, the main central banks started a significant normalisation process of monetary polic<span class=\"_ _4\"></span>y in 2022, starting already in the first quarter<span class=\"_ _0\"></span>, with substantial and repeated increases in the reference interest rate; in the Euro area, the ECB started this process in July 2022, raising the reference rate to 2.5% with four consecutive increases, in July, September<span class=\"_ _3\"></span>, October and December respectively. The context in which the Group operated during 2022 was influenced by the macroeconomic and geopolitical changes that followed the Russian invasion of Ukraine. In this context, the Group was able to operate without interruption and realise planned investments. With reference to indirect consequences, the conflict led to repeated significant increases in reference rates by the main central banks; this resulted in a generalised increase in the cost of debt which, in the case of Snam, went from an average value of 0.8% at 31 December 2021 to an average value of 1.1% at 31 December 2022. Secondly, the growth in reference rates led to a significant increase in the rates used for estimating the recoverable value in the Impairment T<span class=\"_ _0\"></span>est under IAS 36 'Impairment of Assets'.2.<span class=\"_ _4\"></span>3<span class=\"_ _4\"></span> <span class=\"_ _82\"> </span>Effects of the Russia-Ukraine conflict<span class=\"_ _4\"></span>  <span class=\"_ _74\"> </span>on the presentation and measurement<span class=\"_ _4\"></span>  <span class=\"_ _70\"> </span>of items in the consolidated  <span class=\"_ _70\"> </span>financial statements  2.3.1 <span class=\"_ _7\"> </span>Gas Infrastructure\u2022 <span class=\"_ _29\"> </span>Within the T<span class=\"_ _0\"></span>ransportation, Regasification and Storage business, no direct impacts from the Russia-Ukraine conflict are reported at present. With reference to indirect impacts, it should be noted that, pursuant to Decree-Law no. 17 of 1 March 2022, converted with amendments by L. 27 April 2022 , no. 34, setting forth \"Urgent measures for the c<span class=\"_ _0\"></span>ontainment of electricity and natural gas costs, for the devel<span class=\"_ _0\"></span>opment of renewable energies and for the rel<span class=\"_ _0\"></span>aunch of industrial policies\"<span class=\"ff6f\">, the </span>group undertook series of actions aimed at contributing to the achievement of the storage filling targets set by the Ministero dell'<span class=\"_ _3\"></span>Ambiente e della Sicurezza Energetica - MASE, as well as allowing for greater diversification of supply sources. For more details, please refer to the section \"<span class=\"_ _3\"></span>Applicable regulator<span class=\"_ _4\"></span>y framework and principal developments\" in the Director's Report.\u2022 <span class=\"_ _29\"> </span><span class=\"ws0\">In the context of the Sustainable Mobility business, the </span>production and marketing of compressors were impacted by the effects of the Russia-Ukraine conflict where, mainly during the first half of 2022, there were heightened difficulties in procuring some raw materials used in the production phase (such as, for example, stainless steel and components for integrated boards) due to delays in the supply chain. However<span class=\"_ _0\"></span>, the second half of the year saw an upturn in orders for the supply of compressors.Furthermore, with reference to the refuelling station business, the significant increase in methane prices led to a lower growth in consumption and therefore in the supply by the stations; however<span class=\"_ _0\"></span>, the activity of commissioning the stations continued (no. 60 stations as at 31 December 2022 compared to 46 stations to 31 December 2021). 2.3.2 <span class=\"_ _7\"> </span>Energy T<span class=\"_ _0\"></span>ransition\u2022 <span class=\"_ _29\"> </span>In the business of designing and building biomethane plants, the conflict generated difficulties in the procurement of raw materials (especially construction-related materials for IES Biogas), with concomitant price increases and longer delivery times. Biomethane production plants, on the other hand, did not record substantial impacts. However<span class=\"_ _0\"></span>, the continuation of the conflict in 2023 could have further impacts that cannot be determined at present;\u2022 <span class=\"_ _29\"> </span>In the context of the Energy Efficiency business, the generalised increase in the costs of raw materials, due to the Russia-Ukraine conflict, did not have any significant economic effects since, in general, the contracts signed with customers envisage specific indexing that protect companies from price escalation. Nevertheless, there was a slight slowdown in collection times due to the aforementioned cost increase, but with minimal impact. Should this phenomenon continue in the coming months, it could have more significant indirect effects on the working capital and cash flow of the companies. 2.3.3 <span class=\"_ _7\"> </span>Foreign and Italian subsidiariesWith regard to the Snam group's foreign subsidiaries, T<span class=\"_ _3\"></span>AG (jointly controlled company) and GCA (associated company) are the companies most exposed to Russian gas supplies.As of 31 December 2022, the context in which the companies operate has changed significantly compared to the past; despite the presence of a substantially stable regulatory framework, the differences existing with respect to the regulations in force in the main European countries (essentially with reference to the so-called volume risk), generate uncertainties on the expected returns that, based on the current regulatory framework, are largely dependent on the volumes transported.With reference to T<span class=\"_ _0\"></span>AG, the continuation of the Russia-Ukraine conflict, which began in Februar<span class=\"_ _4\"></span>y 2022, led to a significant reduction in gas flows from Russia in the year detected at the Baumgarten entry point<span class=\"_ _4\"></span>, amounting to approximately 52.6% compared to 2021, with a consequent reduction in the volumes imported from the T<span class=\"_ _0\"></span>arvisio entr<span class=\"_ _4\"></span>y point (from approximately 29 bcm in 2021 to approximately 14 bcm in 2022). In addition, around 85% of the long-term transport capacity contracts expired on 31 December 2022. In a scenario characterised by significant uncertainties as to the outcome and duration of the conflict, with actions already taken by some states that will lead to the gradual independence of Europe from Russian gas, Snam determined the estimated recoverable amount of the investment based on a multi-scenario approach, attributing a probability of occurrence to each of the scenarios considered. By multiplying the value in use emerging from each of the scenarios considered by the probability of occurrence attributed to them, the recoverable value was thus determined, resulting in a write-down of the equity investment held in T<span class=\"_ _0\"></span>AG of 340 million euros, with a carrying amount as at 31.12.2022 of 274 million euros.At the same time, the company is actively cooperating with the competent Austrian authorities on the definition of the regulatory framework applicable from 2025 (regulator<span class=\"_ _4\"></span>y period 2025-2028) in light of the changed context in which the company operates.   With regard to GCA<span class=\"_ _4\"></span>, it should be noted that, during 2022, the company used its interconnection points with Germany to ensure the security of supply in Austria and, at the same time, the attainment of the domestic storage fill target. It should also be noted that the company has long-term transport capacity contracts with gradual expiry dates up to 2031.With regard to Italian subsidiaries, there are no direct impacts from the Russia-Ukraine conflict. Lastly, there was a significant and generalised increase in the interest rates used to estimate the recoverable amount in the Impairment T<span class=\"_ _0\"></span>est pursuant to IAS 36 'Impairment of Assets'. <span class=\"_ _30\"></span> <span class=\"_ _1\"></span> <span class=\"_ _1\"></span> 2.4 <span class=\"_ _82\"> </span>Climate change related matters Evidence of the impact of climate change on different industrial sectors has increased considerably in recent years. Many economic sectors will be adversely affected by permanent changes in temperature, precipitation, sea level and more generally by the magnitude and frequency of extreme climate events. In the energy sector<span class=\"_ _0\"></span>, variations in average and extreme temperatures could lead to an increase in energy demand in summer periods and a decrease in demand in winter periods; the final balance will, of course, depend on geographical, socio-economic and technological factors. On the supply side, climate change could adversely affect the energy production infrastructure in some geographical areas. In general, climate risks are systemic risks, which cascade throughout society. The World Economic Forum, in its annual \u2018Global Risks report\u2019 of 2021, considered extreme climate events and failure to act to address the climate crisis to be among the greatest dangers to humanity, both in terms of likelihood of occurrence and impact.The fight against climate change for an increasingly decarbonised economy is the main challenge facing the world today.2.4.1 <span class=\"_ _7\"> </span>Managing climate change risks  and opportunities in SnamThe energy and climate scenarios that form the backdrop to Snam<span class=\"_ _0\"></span>\u2019s activities involve a series of risks and opportunities that must be identified, assessed and managed effectively and promptly. The assessment of<span class=\"_ _0\"></span> the factors that may affect the business is, in fact, an essential condition to be able to continue to operate in the long term in a sustainable manner<span class=\"_ _0\"></span>, namely directing<span class=\"_ _0\"></span> strategies and monitoring changes in the boundary conditions of the same.The risks and opportunities identified by Snam are taken<span class=\"_ _0\"></span> into account in the definition of corporate strategy, with<span class=\"_ _0\"></span> particular reference to objectives in the area of energy transition and decarbonisation and the reduction of greenhouse gas and methane emissions.As part of the integrated management of corporate risks, Snam adopts an Enterprise Risk Management Model (hereinafter ERM) within which the risks associated with climate change are also identified and managed, assessed taking into account the following time horizons:\u2022 <span class=\"_ _33\"> </span>Short-t<span class=\"_ _0\"></span>erm (0-1 year)<span class=\"ff6f\">: in the short-term, Snam<span class=\"_ _0\"></span> </span>creates value by pursuing its business in the manner established by the rules and procedures, with particular focus on risk management and operational efficiency. The main point of reference is the annual budget.\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Medium-term (1-5 years)<span class=\"ff6f\">: in the medium term, the </span></span>ability to carry out investment programmes, thereby ensuring a flow of resources and that favourable economic conditions are maintained, is also important. The main point of reference is the<span class=\"ff63\"> Strategic Plan,<span class=\"_ _0\"></span> </span>which cov<span class=\"_ _0\"></span>ers a period of up to five years<span class=\"ff6f ls0\">. </span>\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Long-term (5-10 years)<span class=\"ff6f\">: in the long-term, it is vital that </span></span>the investment decisions and strategic choices made have interpreted trends in the best way possible. The main point of reference is the <span class=\"ff63\">T<span class=\"_ _3\"></span>en-year transportation </span>network development plan<span class=\"ff6f\"> submitted to the<span class=\"_ _0\"></span> </span>Authority, which covers a period of 10 years.Snam\u2019s ERM model envisages assessment cycles, the results of which are shared with the Leadership T<span class=\"_ _0\"></span>eam, the Control and Risk and Related-Party T<span class=\"_ _0\"></span>ransactions Committee, the Board of Statutory Auditors and the Super<span class=\"_ _4\"></span>visory Board. On an annual basis, the Board of Directors, together with the ESG Committee, is also updated on these topics in order to integrate climate change topics into the planning and definition of strategies for the management of ESG topics relevant to the Group.The risks are explained in the Director's Report , in the section \"Elements of risk and uncertainty\", where a detailed analysis was carried out on climate change risks.2.4.2 <span class=\"_ _7\"> </span>Climate change related risksIn accordance with the recommendations of the T<span class=\"_ _0\"></span>ask Force on Climate Related Financial Disclosure (TCFD), climate change subjects companies to two types of risks: physical risks, due directly to weather and climate variations, and transition risk, related to the socio-economic reaction of society to climate change.Physical risks <span class=\"ff6f\">are divided into: </span>\u2022 <span class=\"_ _29\"> </span>acute risks, related to the increase in the severity of extreme weather phenomena, which may cause material damage to the infrastructure, with impacts on the continuity and quality of the service; \u2022 <span class=\"_ _29\"> </span>chronic risks, which are more predictable and which Snam associates mainly with the increase in temperature with a consequent lower demand for gas.T<span class=\"_ _0\"></span>ransition risks<span class=\"ff6f\"> are divided into:</span>\u2022 <span class=\"_ _29\"> </span>compliance risk, in terms of the tightening of the reference and emerging regulatory framework to accelerate the reduction of pollutant and climate-changing emissions;\u2022 <span class=\"_ _29\"> </span>mark<span class=\"_ _0\"></span>et risk, in terms of increased penetration of renewable energies to the detriment of natural gas, alternative uses of gas and the development of new businesses (biomethane, etc.) and/or the CNG market, as well as the behaviour of consumers, financiers and investors, who are increasingly oriented towards sustainable products; \u2022 <span class=\"_ _29\"> </span>technological risks, in terms of diffusion of new technologies fostering the use of intermittent energy sources and the need to adapt to new technological standards.  2.4.3 <span class=\"_ _7\"> </span>Actions undertaken by Snam: from  the development of new businesses,  <span class=\"_ _ad\"> </span>directly associated with the commitment  to energy transition, to interventions  on regulated infrastructuresWith regard to physical risks, Snam continually monitors the integrity of its infrastructure and plants, as well as the state of health and conservation of the areas in which they are located, constantly updating the processes and systems used in order to identify, with increasing notice, any critical issues through the introduction of new technologies that can also reduce the environmental impact of the activities themselves. These actions allow the company to limit its exposure to risks associated with chronic natural events. In addition, in order to remedy unforeseeable extreme natural events, Snam has adopted innovative intervention strategies and action plans aimed at ensuring immediate safety and the restoration of activities in the shortest possible time.Snam also has specific insurance contracts in place to cover some of these risks, in line with industry best practices.With reference to the risks of transition, Snam has, in recent years, begun repurposing its infrastructure, developed its international presence, formed a large number of partnerships and launched numerous energy transition initiatives. Building on its consolidated capabilities in regulated businesses and expertise in green gas and new energy transition trends, the company is evolving towards a multi-commodity infrastructure concept, i.e. capable of transporting and storing different types of gas, leveraging and continuing to develop its hydrogen, CO, biomethane, mobility and energy 2efficiency businesses.In this context, in Januar<span class=\"_ _4\"></span>y 2023, the new 2022-2026 Strategic Plan and the long- T<span class=\"_ _0\"></span>erm Vision to 2030 were presented, with which Snam underlined its contribution to supporting the great transformation underway in the energy sector<span class=\"_ _0\"></span>, leveraging on the enabling role of infrastructure to achieve a fully decarbonised economy through a plan of increasing investments. The Strategic Plan envisages investments totalling 10 billion euros over the next four years (up 23% compared to the previous plan), mainly including maintenance, modernisation and infrastructure development activities. In addition, investments of 1 billion euros are planned to achieve carbon neutrality and energy transition. The pillars of Snam's Carbon Neutrality strategy are detailed in the chapter \"Strategy and Risk Management - T<span class=\"_ _0\"></span>owards carbon neutrality\" of the Directors' Report.Specifically, Snam plans to reduce Scope 1 and Scope 2 greenhouse gas emissions by 28% by 2025, 40% by 2027 and 50% by 2030 (vs. 2018), to achieve carbon neutrality by 2040. The Company also set a target on natural gas emissions of -55% by 2025 and -65% by 2030 (both vs. 2015).For these reasons, it is believed that, at present, the Group has a limited exposure to the impact that possible climate risks could have on the valuation of non- current assets and other assets, including receivables, recognised in the financial statements, also in consideration of the specific business and segments in which it operates.Similarly, due to the systematic monitoring of its assets and the areas on which they insist, the Company is able to identify in advance possible situations that could potentially generate potential liabilities related to climate risks.3ACCOUNTING ST<span class=\"_ _1\"></span>ANDARDS <span class=\"_ _0\"></span>AND<span class=\"_ _0\"></span> INTERPRET<span class=\"_ _32\"></span>A<span class=\"_ _3\"></span>TIONS <span class=\"_ _3\"></span>APPLICABLE FROM <span class=\"_ _0\"></span>2<span class=\"_ _3\"></span>02<span class=\"_ _3\"></span>2For the financial year ended 31 December 2022, the Group applied accounting standards in line with those of the previous year<span class=\"_ _0\"></span>, with the exception of the accounting standards and interpretations which came into force in the year<span class=\"_ _0\"></span> starting on 1 January 2022, which are described below.By Regulation no. 2021/1080, issued by the European Commission on 28 June 2021, the regulatory provisions contained in the following documents were approved:\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Amendments (i) to IFRS 3 Business Combinations; (ii) to IAS 16 Property, Plant and Equipment; (iii) to IAS 37 </span>Provisions, Contingent Liabilities and C<span class=\"_ _0\"></span>ontingent Assets\u201d.

(ii) Amendments to IAS 16: the document \u201c<span class=\"_ _3\"></span>Amendments to IA<span class=\"_ _4\"></span>S 16 Property, Plant and Equipment: Proceeds before intended use\u201d introduced some clarifications, specifying that it is not allowed to deduct from the cost of the fixed asset the amount received from the sale of goods produced before the asset was ready for use, as intended by management. These sales revenues and related costs shall therefore be recognised in the income statement. (iii) Amendments to IAS 37: the document\u201c<span class=\"_ _0\"></span>Amendments to IAS 37 Provisions, Contingent Liabilities and Contingent Assets: Onerous contracts - Cost of fulfilling a contract\u201d clarified which cost items are to be considered in determining whether or not a contract will be loss-making.  \u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Improvements to IFRS (2018-2020 cycle):</span>(i) amendments to IFRS 1 \"First<span class=\"_ _0\"></span>-time Adoption of International Financial Reporting Standards\", in relation to the measurement of cumulative translation differences; (ii) amendments to IFRS 9 \"Financial Instruments\" clarifying which fees (commissions) are to be included when performing the \"10 per cent\" test required by paragraph B3.3.6 of IFRS 9, specifying that only fees, paid or received, between the entity and thelender; (iii) deletion of Illustrative Example 13 of IFRS 16 \"Leases\" relating to the repayment of leasehold improvements by the lessor in order to remove any doubt about the treatment of lease incentives; and (iv) amendments to IAS 41; the amendment removes the requirement in paragraph 22 of IA<span class=\"_ _4\"></span>S 41 that entities when measuring a biological asset at fair value using present value techniques must exclude cash flows of a tax nature from the measurement. This will ensure consistency with the requirements of IFRS 13.The adoption of these amendments did not have effects on the Group\u2019s consolidated financial statements.4FINANCIAL<span class=\"_ _0\"></span> ST<span class=\"_ _32\"></span>A<span class=\"_ _32\"></span>TEMENTSWith reference to the financial statements, note that:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">the items in the Statement of financial position are classified by distinguishing assets and liabilities on a current/non-</span>1current basis\u201d;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">the Income Statement has been presented separately from the Comprehensive Income Statement and classifies </span>costs by type, since this is deemed to be the best way of representing the Group\u2019s operations and is in line with the established practice of companies operating in international markets;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">the Cash Flow Statement has been prepared using the indirect method.</span>Moreover<span class=\"_ _0\"></span>, pursuant to Consob Resolution No. 15519 of 28 July 2006, any income and expense from non-recurring operations is shown separately in the income statement.With regard to the same Consob Resolution, the balances of receivables/payables and transactions with related parties, described in more detail in Note 37 \u2013 \u201cRelated-party transactions\u201d, are shown separately in the financial statements.1 <span class=\"_ _48\"> </span>Assets and liabilities are classified as current if: (i) their realisation/settlement is part of the normal operating cycle of the company or in the 12 months after the financial year-end; (ii) they consist of the cash and cash equivalents without restrictions that would limit usage thereof in the 12 months following the closure of the year; or (iii) they are held mainly for trading.5SIGNIFICANT ACCOUNTING<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>ST<span class=\"_ _32\"></span>ANDARDS  The most significant measurement criteria adopted when preparing the consolidated financial statements are described below.5.1 <span class=\"_ _82\"> </span>Consolidation CriteriaSubsidiaries, joint ventures, associates and other significant equity investments are indicated separately in the appendix \u201cEquity investments of Snam S.p.<span class=\"_ _4\"></span>A. as at 31 December 2022\u201d, which is an integral part of these notes. The same annex shows the changes in the scope of consolidation at 31 December 2022 compared to 31 December 2021. For further details on the acquisition of controlling interests, for which the conditions for the application of IFRS 3 exist, please refer to the section \u201cBusiness combinations\u201d. All the financial statements of the companies included in the scope of consolidation are expressed in euro, adjusted, where necessary, to make them consistent with the accounting principles applied by the Parent Company<span class=\"_ _0\"></span>.<span class=\"ls0\"> </span>Fully consolidated subsidiariesThe Group defines another entity as a subsidiary when it:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">has the power to make decisions concerning the investee entity;</span>\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">is entitled to receive a share of or is exposed to the variable profits and losses of the investee entity;</span>\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">is able to exercise power over the investee entity in such a way as to affect the amount of its economic returns.</span>Figures relating to subsidiaries are included in the consolidated financial statements, based on standardised accounting principles, from the date on which the Company assumes direct or indirect control over them until the date on which said control ceases to exist. The assets, liabilities, income and expenses of consolidated companies are fully incorporated line-by-line in the consolidated financial statements (full consolidation method). Unrealised gains from transactions between consolidated companies are derecognised, as are receivables, payables, income, expenses, guarantees, commitments and risks between consolidated companies. The portion pertaining to the Group of unrealised gains with companies valued using the equity method is derecognised. In both cases, intragroup losses are not derecognised because they are considered to represent the impairment loss on the transferred asset.Changes in equity investments held directly or indirectly by the Company in subsidiaries that do not result in a change in the qualification of the investment as a subsidiary are recorded directly in equity as transactions with shareholders. The book value of the equity attributable to Parent company shareholders and non-controlling interests are adjusted to reflect the change in the equity investment ownership. The difference between the book value of minority interests and the fair value of the consideration paid or received is recorded directly under equity attributable to Parent company shareholders.Otherwise, the selling of interests entailing loss of control requires the posting to the income statement of: (i) any capital gains or losses calculated as the difference between the consideration received and the corresponding portion of shareholders\u2019 equity transferred; (ii) the effect of the alignment to the fair value of any residual equity investment maintained; (iii) any amounts posted to other components in the comprehensive income statement relating to the former subsidiary that will be reclassified to the income statement<span class=\"_ _4\"></span>. The fair value of any equity investment maintained<span class=\"_ _0\"></span> at the date of loss of control represents the new reference value for the successive valuation of the equity investment according to the applicable valuation criteria.Associates and joint ventures accounted for using the equity methodAn associate is an investee in which the Group has significant influence, i.e., the power to participate in determining the financial and operating policies of the associate company, without, however<span class=\"_ _0\"></span>, having control or 2joint control over it. It is assumed that the investor has significant influence (unless there is proof to the contrary) which is presumed to exist when the investment held is at least 20% of the exercisable voting rights.A joint venture is a joint arrangement in which the parties that hold joint control have rights to the net assets subject to the arrangement and, therefore, have an interest in the jointly controlled corporate vehicle.Equity investments in associates and joint ventures are measured using the equity method, whereby the investments are initially recognised at cost and subsequently adjusted to take account of:(i) <span class=\"_ _34\"> </span>the investor<span class=\"_ _4\"></span>\u2019s share in the economic results of the investee after the acquisition date;(ii) <span class=\"_ _e\"> </span>the investor\u2019s share of the other components in the comprehensive income statement of the investee.Dividends distributed by the investee are recognised net of the book value of the equity investment. For the purposes of applying the equity method, the adjustments provided for the consolidation process are taken into account (see also the previous point on fully consolidated subsidiaries).The sale of investment that results in loss of joint control or significant influence over the investee determines the recognition of the following in the income statement: (i) any capital gains or losses calculated as the difference between the consideration received and the corresponding fraction of the book value of the investment sold; (ii) the effect of the alignment to the fair value of any residual equity investment maintained; (iii) any amounts posted to other components in the comprehensive income statement relating to the investee entity that will be reclassified to the income statement. The value of any equity investment maintained, aligned with the relative fair value at the date of loss of joint control or significant influence, represents the new reference value for the successive valuation according to the applicable valuation criteria. If there is objective evidence of impairment, the Group performs an impairment assessment  by comparing the book value with the related recoverable amount and recognises the difference in the income statement under \u201cShare of profit or loss of investments accounted for using the equity method\u201d. If the Group\u2019s share of the loss exceeds the book value of the investment, the latter is written 2 <span class=\"_ _48\"> </span>Joint control is the contractual sharing of control pursuant to an agreement, which exists only where the unanimous consent of all the parties that share power is required for decisions relating to significant activities.off and any excess is recognised in a specific provision, if the investor is obliged to meet the legal or constructive obligations of the investee or otherwise cover its losses. When the reasons for the impairment losses no longer apply, equity investments are revalued up to the amount of the impairment losses entered, with the effect posted to the income statement under the above item.The parent company\u2019s share of any losses of the investee company, greater than the investment\u2019s book value, is<span class=\"_ _0\"></span> recognised in a special provision to the extent that the parent company is committed to fulfilling its legal or implied obligations to the investee, or<span class=\"_ _0\"></span>, in any event, to covering its losses.<span class=\"ls0\"> </span>Business combinationsBusiness combinations are transactions with which the group acquires control of a business. T<span class=\"_ _0\"></span>o determine whether a particular set of acquired assets and activities meets the definition of a \u201cbusiness\u201d, the Group examines whether that set comprises, at least, a production factor and a substantial process and whether it has the ability to generate production. Business combinations are accounted for by applying the acquisition method, whereby the consideration transferred at the date of acquisition of control is equal to the fair value of the assets transferred, the liabilities incurred or taken on, and any equity instruments issued.<span class=\"_ _0\"></span> The consideration transferred also includes the current value of any deferred fixed payments and the fair value of any contingent considerations (e.g earn-outs). If the<span class=\"_ _0\"></span> contingent consideration meets the definition of an equity instrument, it is classified as shareholders\u2019 equity and is not measured thereafter<span class=\"_ _0\"></span>. Other contingent considerations are recognised as a liabilities and are measured at fair value at each financial year-end; changes in fair value are<span class=\"_ _0\"></span> recognised in the income statement.Costs directly attributable to the transaction, other than those related to the issue of debt or equity instruments, are recognised in the income statement when they are incurred.The shareholders\u2019 equity of these associate companies is determined by attributing to each asset and liability its fair value at the date of acquisition of control. If positive, any difference from the consideration transferred is posted to the asset item \u201cGoodwill\u201d; if negative, it is posted instead to the income statement.Where total control is not acquired, the share of equity attributable to minority interests is determined based on the share of the current values attributed to assets and liabilities at the date of acquisition of control, net of any goodwill (the \u201cpartial goodwill method\u201d). Alternatively, the full amount of the goodwill generated by the acquisition is recognised, therefore also taking into account the portion attributable to minority interests (the \u201cfull goodwill method\u201d). In this case, non-controlling interests are expressed at their total fair value, including the attributable share of goodwill. The choice of how to determine goodwill (Partial goodwill method or full goodwill method) is based on each individual business combination transaction.If control is assumed in successive stages, the consideration transferred is determined by adding together the fair value of the equity investment previously held in the acquired company and the amount paid to acquire the additional equity investment. The difference between the fair value of the previously held equity investment (redetermined at the time of acquisition of control) and the relative book value is posted to the income statement. Upon acquisition of control, any components previously recognised under other components in the comprehensive income statement are posted to the income statement or to another item of shareholders\u2019 equity, if no provisions are made for classification in the income statement.When the values of the assets and liabilities of the acquired entity are determined provisionally in the financial year in which the business combination is concluded, the figures recorded are adjusted, with retroactive effect, no later than 12 months after the acquisition date, to take into account new information about facts and circumstances in existence at the acquisition date.Business combinations involving entities under joint controlBusiness combinations involving companies that are definitively controlled by the same company or companies before and after the transaction, and where such control is not temporary, are classed as \u201cBusiness combinations of entities under common control\u201d, whose accounting is not specifically disclosed in IFRSs.  In the absence of a reference accounting standard, the selection of an accounting standard for such transactions, for which a significant influence on future cash flows cannot be established, is guided by the principle of prudence, which leads to the application of the criterion of continuity of values of the net assets acquired. The assets are measured at the book values from the financial statements of the companies being acquired (or the vendor company) before the transaction or<span class=\"_ _0\"></span>, alternatively, at the values from<span class=\"_ _0\"></span> the consolidated financial statements of the common ultimate parent.With regard to the sale of business, the treatment of the difference between the contractually defined consideration and the carrying amounts of the transferred business is differentiated depending on the entities involved in the transfer<span class=\"_ _0\"></span>.With regard to contributions involving businesses under common control, on the other hand, irrespective of the pre-existing investment relationship, the transferee entity recognises the transferred business at its historical carrying value, increasing its own equity by an equal amount; the transferring entity shall recognise the investment in the transferee entity at an amount equal to the increase in the latter\u2019s shareholders\u2019 equity. This accounting treatment refers to the proposal by Assirevi in the Preliminary Guidelines on IFRS (OPI No. 1 Revised) - \u201c<span class=\"_ _3\"></span>Accounting treatment of business combinations of entities under common control in the separate and consolidated financial statements\u201d issued in October 2016.<span class=\"ls0 ws0\"> </span>Accounting treatment of put options written on the shares of subsidiariesTherefore, if the Group does not have the unconditional right to avoid delivery of cash or other financial instruments when a put option on shares in subsidiaries is exercised, a financial liability equal to the current value of the option exercise price is recognised and subsequent changes in the financial liability are recognised in the income statement. The same accounting treatment is applicable when, in addition to a put option, there is also the simultaneous presence of a symmetrical call option, the so-called \u201csymmetrical put and call options related to non-controlling interest\u201d.Snam considers that shares subject to put options (or symmetrical put and call options) have already been acquired by the Group, in cases where the economic benefits and risks associated with the actual ownership of the shares do not remain with the minority shareholders; therefore, in such circumstances, it does not recognise minority interests in the consolidated financial statements.5.2 <span class=\"_ _82\"> </span>Property<span class=\"_ _3\"></span>, plant and equipment  Recognition and measurement of property assetsProperty, plant and equipment are measured at cost, less accumulated depreciation and impairment losses. When a significant period of time is needed before the asset is ready for use, financial expenses incurred during the asset preparation period are also capitalised in the cost of the asset.If there are current obligations for dismantling and removal the assets and restore the sites, the book value includes the estimated (discounted) costs to be incurred at the time that the structures are abandoned, recognised as a contra-entry to a specific provision. The accounting treatment for revisions in these cost estimates, the passage of time and the discount rate are indicated in the Note 5.9 \u201cProvisions for risks and charges, contingent liabilities and contingent assets\u201d.Subsequent costs of improvements, upgrades and transformations to/ of property, plant and equipment are capitalised when it is likely that they will increase the future economic benefits expected. Costs are also capitalised when related to items purchased for security or environmental reasons which, although not directly improving the future economic benefits of existing assets, are necessary to carr<span class=\"_ _4\"></span>y out the company\u2019s operations.Property, plant and equipment includes:  (i) <span class=\"_ _16\"> </span>with regard to natural gas transportation, the value relating to the quantities of natural gas injected to bring natural gas pipelines into service. The valuation is carried out using the weighted average purchase price method. Specifically, the component of this quantity that can no longer be extracted (the \u201cinitial line pack\u201d) is depreciated over the useful life of the plant to which it refers. On the contrary, the commercial component, which is eventually transferable to the market or can be put to alternative uses (the so-called \u201cOperating line pack\u201d), is not subject to depreciation, since by its nature it cannot depreciate; (ii) <span class=\"_\"> </span>in the context of natural gas storage, the part of the gas injected into the storage wells as cushion gas.Recognition and measurement of leased assetsA contract is or contains a lease if it gives an entity the right to control the use of an identified asset for a certain period of time in exchange for a fee. For all leases that run for more than 12 months, relating to non- low value 3assets, the following elements are recognised in the balance sheet at the effective date, i.e. when the asset is available for use:(i) an asset, under Property, plant and equipment, representing the right to use the asset, and (ii) a financial liability, representing the obligation to make<span class=\"_ _0\"></span> 3 <span class=\"_ _48\"> </span>The Group considers low-value assets to be all assets worth 25 thousand euros or less. the payments under the contract (also referred to as the \u201clease liability\u201d). In determining the duration of the lease, the group considers the non-cancellable period of the contract and, when it believes there is reasonable certainty, also the additional periods for the exercise of renewal options or the non-exercise of early termination options provided in the contract.Liabilities for leases are recognised initially at an amount equal to the current value of the following lease payments not yet made at the lease commencement date:  (i) <span class=\"_ _16\"> </span>fixed (or substantially fixed) payments, net of any incentives to be received; (ii) <span class=\"_\"> </span>variable payments that depend on trends in rates or indices;(iii) estimated future payments for any residual value guarantees, for the exercise of the purchase option and for any penalties related to the early termination of the contract, if the group considers the exercise of such options to be reasonably certain.The current value of the payments is calculated using a discount rate equal to the group\u2019s marginal borrowing rate taking into account the frequency and duration of payments under the lease agreement.Subsequent to initial recognition, the lease liability is measured at amortised cost and is redetermined, against the book value of the right<span class=\"_ _0\"></span>-of-use asset, when there is a change in the lease payments due as a result of: (i) <span class=\"_ _16\"> </span>contract renegotiations;(ii) <span class=\"_\"> </span>changes in rates or indices;  (iii) changes in measurement made regarding the exercise of contractually-provided options (e.g. purchase of the leased asset or the extension or early termination of the contract).The right<span class=\"_ _0\"></span>-of-use asset is initially recognised at cost, determined as the sum of the following components: (i) <span class=\"_ _16\"> </span>the initial amount of the finance lease liability; (ii) <span class=\"_\"> </span>the initial direct costs incurred by the lessee; (iii) any payments made on or before the lease commencement date, net of any incentives received by the lessor; (iv) the best estimate of the costs that the group expects to incur for the dismantling and removal of the asset and for the possible restoration of the site (i.e. the costs for restoring the asset to the conditions established in the contract). After the initial recognition, the right<span class=\"_ _0\"></span>-of-use asset is adjusted to take account of:(i) <span class=\"_ _16\"> </span>depreciation and amortisation expense;(ii)  the related effects and any restatements of the financial lease liability; (ii) <span class=\"_\"> </span>the related effects and any restatements of the financial lease liability.Depreciation of property<span class=\"_ _3\"></span>, plant and equipment  Starting when the asset is available and ready for use, owned and leased property, plant and equipment is systematically depreciated on a straight<span class=\"_ _0\"></span>-line basis over its useful life, defined as the period of time in which it is expected that the company may use the asset. The amount to be depreciated is the book value, reduced by the projected net realisable value at the end of<span class=\"_ _4\"></span> the asset\u2019s useful life, if this is significant and can be reasonably determined.The table below shows the annual depreciation rates used for the year in question, broken down into homogeneous categories, 4together with the relevant period of application:Annual economic<span class=\"_ _0\"></span>-technic<span class=\"_ _0\"></span>al depreciation rat<span class=\"_ _0\"></span>e (%) Land<span class=\"_ _2f1\"> </span><span class=\"ff69\">not depreciated</span>Buildings<span class=\"_ _2f2\"> </span><span class=\"ff69\">2</span>Plant and machinery \u2013 Transportation- Methane pipelines <span class=\"_ _1de\"> </span>2 or higher depending on the residual useful life- Compression stations<span class=\"_ _1fb\"> </span>5 or higher depending on the residual useful life- Gas reduction and regulation plants<span class=\"_ _2c2\"> </span>5 or higher depending on the residual useful life- Radio links<span class=\"_ _2f3\"> </span>25-Monitoring and control instruments and syst<span class=\"_ _0\"></span>ems<span class=\"_ _271\"> </span>5 or higher depending on the residual useful lifePlant and machinery \u2013 Storage- Pipelines<span class=\"_ _2f4\"> </span>2- T<span class=\"_ _0\"></span>reatment plants <span class=\"_ _fb\"> </span>4- Compression stations<span class=\"_ _2f5\"> </span>5- Storage wells<span class=\"_ _2f6\"> </span>1.66-Monitoring and control instruments and syst<span class=\"_ _0\"></span>ems<span class=\"_ _1e9\"> </span>5Plant and machinery \u2013 regasification- Regasification plants <span class=\"_ _1e0\"> </span>4 or higher depending on the residual useful life- T<span class=\"_ _0\"></span>anks and oil pipelines<span class=\"_ _15b\"> </span>4 or higher depending on the residual useful lifePlant and machinery - Biogas/Biomethane- Biogas/biomethane plants<span class=\"_ _a8\"> </span>6.7 or depending on the duration of the concessionOther assetsCentralised IT infrastructures<span class=\"_ _291\"> </span>20Other plant and equipment<span class=\"_ _2f7\"> </span>2.5-12.5Measuring equipment<span class=\"_ _2f8\"> </span>5Industrial and Commercial Equipment<span class=\"_ _282\"> </span>10-35Other assets<span class=\"_ _2f9\"> </span>10-33Rights of use for leased assets<span class=\"_ _20e\"> </span><span class=\"ff69\">&lt; between economic-t<span class=\"_ _0\"></span>echnical life and contract duration</span>When an item recorded under property, plant and equipment consists of several significant components with different useful lives, a component approach is adopted, whereby each individual component depreciates separately.4 <span class=\"_ _48\"> </span>The application rate or internal could be higher depending on the residual life following business combination acquisitions and/or transactions. 5.3 <span class=\"_ _82\"> </span>Intangible assets and goodwillRecognition and measurement of intangible assets and goodwillIntangible assets are those non monetary assets without identifiable physical form, are controlled by the group and are capable of generating future economic benefits. They are recognised at cost net of amortisation and any accumulated impairment losses.Goodwill arising from the acquisition of subsidiaries is measured at cost less impairment losses cumulated.T<span class=\"_ _0\"></span>echnical development costs are capitalised as intangible assets when: (i) the cost attributable to the intangible asset can be reliably determined; (ii) there is the intent, availability of financial resources and technical capability to make the asset available for use or sale; and (iii) it can be shown that the asset is capable of producing future economic benefits.Alternatively, costs for the acquisition of new knowledge or discoveries, investigations into products or alternative processes, new techniques or models, or the design and construction of prototypes, or incurred for other scientific research or technological developments, which do not meet the conditions for capitalisation are considered current costs and charged to the income statement for the period in which they are incurred.The book value of the storage concessions represents the reserves of natural gas in the fields (so-called cushion gas), which does undergo depreciation, because: (i) <span class=\"_ _16\"> </span>the volume of this gas is not changed by the storage activity; (ii) <span class=\"_\"> </span>the economic value of the gas that can be recovered at the end of the concession, in accordance with the provisions of the Ministerial Decree of 3 November 2005 \u201cCriteria for determining an adequate consideration for the remuneration of assets allocated to a concessionaire for the storage of natural gas\u201d of the Ministry of Productive Activities (MAP), is not less than the value recorded in the financial statements.Amortisation of intangible assets with finite useful life Intangible assets with a finite useful life are amortised systematically over their useful life, which is understood to be the period of time in which it is expected that the company may use the asset.The table below shows the annual depreciation rates used for the year in question, broken down into homogeneous categories, together with the relevant period of application:Annual economic<span class=\"_ _0\"></span>-technic<span class=\"_ _0\"></span>al depreciation rat<span class=\"_ _0\"></span>e (%) Storage concessions<span class=\"_ _163\"> </span><span class=\"ff69\">non-amortised: residual value greater than book value</span>Information systems<span class=\"_ _2fa\"> </span><span class=\"ff69\">20-33</span>Other intangible fixed assets<span class=\"_ _186\"> </span><span class=\"ff69\">20 or based on the duration of the contract</span>5.4 <span class=\"_ _82\"> </span>Public and private grantsCapital grants given by public authorities are recognised when there is reasonable certainty that the conditions imposed by the granting government agencies for their allocation will be met, and they are recognised as a reduction to the purchase or production cost of their related assets. Similarly, capital grants received from private entities are recognised in accordance with the same regulatory provisions.Operating grants are recognised in the income statement on an accruals basis, consistent with the relative costs incurred.5.5<span class=\"_ _0\"></span> <span class=\"_ _82\"> </span>Impairment of non-financial assets  Impairment of tangible and intangible assets with finite useful lifeAt least once a year<span class=\"_ _0\"></span>, non-financial, tangible and intangible assets with a finite useful life are analysed to uncover any indicators of impairment. When there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of property, plant and equipment or intangible assets with a finite useful life, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs(see paragraph 5.8 \u201cMeasurement at fair value\u201d), or the value in use, whichever is greater<span class=\"_ _3\"></span>.The recoverable amount, in the value in use configuration, is determined by discounting projected cash flows resulting from the use of the asset and, if they are significant and can be reasonably determined, from its sale at the end of its useful life, net of any disposal costs.With reference to the T<span class=\"_ _0\"></span>ransportation (Snam Rete Gas), Regasification (LNG) and Storage (Stogit) C<span class=\"_ _0\"></span>GUs, the recoverable value was defined as corresponding to the estimated value of the Net Invested Capital recognised to these assets for tariff 5purposes (R<span class=\"_ _4\"></span>AB - Regulatory Asset Base) by the Regulatory Authority for Energy, Networks and the Environment (ARER<span class=\"_ _4\"></span>A), net of the flat<span class=\"_ _0\"></span>-rate components, of the Employee Severance Indemnity (TFR) and of the contributions received.The measurement is made on a per-asset basis or for the smallest identifiable set of assets that, through its own continuous use, generates cash inflows that are largely independent of those of other assets or groups of assets (Cash Generating Units - CGUs). Expected cash flows are determined on the basis of reasonable and documentable assumptions representative of the best estimate of the future economic conditions of the asset or groups of assets, giving greater importance to indications from the outside. Discounting is done at a rate reflecting current market conditions for the time value of money and specific risks of the asset not reflected in the estimated cash flows. If the book value of the asset or CGU is greater than its recoverable amount, an impairment loss is recognised in the income statement; a CGU\u2019s impairment losses are first recognised as a reduction in the book value of any goodwill (see next point \u201cImpairment of goodwill and intangible assets not yet available for use\u201d) allocated to it and then as a reduction in the book value of the other assets of the CGU, in proportion to their respective carrying amounts. The book value of each Cash Generating Unit (or grouping of CGUs), consistently with the prevailing valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test<span class=\"_ _4\"></span>.If the conditions for a previously effected impairment no longer apply, the book value of the asset (except for goodwill) is restored with recognition in the income statement (recovery of value), within the limits of the net book value that the asset in question would have had if the impairment had not been carried out and any related amortisation had been carried out.    If certain specific assets held by the Group are affected by unfavourable operating or economic conditions that may compromise their ability to contribute to the realisation of cash flows, they may be subject to an independent recoverability analysis and impaired, if necessary. Impairment of goodwill,  intangible assets with an indefinite useful life and intangible assets not yet available for use.The recoverability of the book value of goodwill, of intangible assets with an indefinite useful life and intangible assets not yet available for use is tested at least annually, and in any case when events occur leading to an assumption of<span class=\"_ _0\"></span> impairment.Pursuant to the provisions of IFRS 3, in the context of business combinations, the acquirer<span class=\"_ _0\"></span>, at the acquisition date, recognises all assets, liabilities and identifiable contingent liabilities under the acquisition at their fair values; any remaining positive difference with respect to the acquisition cost is recognized in the asset item Goodwill, and any negative difference is recognised in the income statement.5 <span class=\"_ _48\"> </span>The RAB is the reference basis for the determination of the ser<span class=\"_ _4\"></span>vice tariffs and, therefore, of the cash flows generated by the activities. The value of the RAB is defined through the historical cost method revalued as regards the Fixed capital, and on a flat rate basis for the working capital, the employee severance indemnity and, with reference to the storage segment, the provision for decommissioning and site restoration.For the purpose of the impairment test, goodwill is allocated, as from the date of acquisition, to each Cash Generating Unit, or group of CGUs, that is expected to benefit from the synergies of the combination. After its initial recognition, goodwill is not amortised but is instead subject to a recoverability test at least annually by determining the recoverable value of the CGU or group of CGUs to which it is allocated (following the procedures described in the note \u201cImpairment of tangible and intangible assets of finite useful life\u201d); this is then compared to the book value of the CGU itself (or group of CGUs). The book value of each Cash Generating Unit<span class=\"_ _0\"></span> (or grouping of CGUs), consistently with the prevailing<span class=\"_ _0\"></span> valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test.When the book value of the CGU (or group of CGUs<span class=\"_ _0\"></span>), including the goodwill attributed to it, exceeds the recoverable value, the difference is subject to impairment, which is attributed by priority to the goodwill up to its amount; any surplus in the impairment with respect to the goodwill is attributed pro rata to the book value of the assets constituting the CGU (or group of CGUs<span class=\"_ _0\"></span>). Goodwill write-downs are not reversed, even if the reasons for the write- down no longer apply in subsequent years.<span class=\"ls0\"> </span>Reduction in value of Equity investmentsWhen there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of investments, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs (see paragraph 5.8 \u201cMeasurement at fair value\u201d), and the value in use, determined through the application of the 6Dividend Discount Model (DDM) or Discounted Cash Flow(DCF) method, (the present value of the expected cash flows is determined in accordance with the provisions of the previous paragraph \u201cImpairment of tangible and intangible assets with a finite useful life\u201d). The application of the Dividend Discount Model (DDM) provides that the recoverable value, in the configuration of the value in use, is determined by discounting the expected dividend flows on the basis of the forecast plans of the investee companies drawn up according to reasonable and documentable assumptions, discounted at the cost of the capital (Ke) which includes an<span class=\"_ _0\"></span>y specific risks not reflected in the estimated cash flows.6 <span class=\"_ _48\"> </span>If the Discounted Cash Flow (DCF) method is used, the results are adjusted for the respective net financial positions.5.6 InventoriesInventories, including compulsory inventories, are recorded at the lower of purchase or production cost and net realizable value, which is the amount that the entity expects to receive from their sale in the normal course of business, net of the estimated costs for the completion and the realisation of the sale.The cost of natural gas inventories is determined using the weighted average cost method.It should be noted that any transactions involving strategic gas, which are subject to prior authorisation by the MED, entail a withdrawal and subsequent replenishment of the quantities of gas from the strategic reserve, not resulting in 7any movement of the stock.  5.7 <span class=\"_ _82\"> </span>Financial instrumentsFinancial instruments are defined as any contract that gives rise to a financial asset, financial liability or equity instrument, which are recognized and measured in accordance with IAS 32 \"Financial Instruments: Presentation\" and IFRS 9 \"Financial Instruments.\" Financial instruments include, cash and cash equivalents, short<span class=\"_ _0\"></span>-term and long-term financial receivables and payables, trade receivables and payables, bonds held and issued, equity investments that do not constitute control, associates or joint control (so-called minority interests) and derivative instruments.Cash and cash equivalentsCash and cash equivalents include cash amounts, on demand deposits, and other short<span class=\"_ _0\"></span>-term financial assets with a term of less than three months, which are readily convertible into cash and for which the risk of a change in value is negligible. They are recorded at nominal value, corresponding to fair value.Financial assets - Initial recognitionA financial asset (or financial liability) is recognized in the financial statements when, and only when, the Group becomes a party to the contractual terms of the instrument (i.e., at the trade date).Initial recognition is at fair value, increased, for financial assets other than those measured at fair value with the effects charged to the income statement, by directly attributable transaction costs. For trade receivables without a significant financial component, the initial recognition value of which is the transaction price (as defined by IFRS 15).7 <span class=\"_ _48\"> </span>Or the risk, the timing or the amount of the future cash flows of the entity are not intended to change following these transactions (IFRS 15.9d)At initial recognition, financial assets are classified into the following categories: (i) financial assets measured at amortized cost; (ii) financial assets measured at fair value with the effects charged to other comprehensive income (hereinafter also FV<span class=\"_ _4\"></span>TOCI); and (iii) financial assets measured at fair value with the effects charged to the income statement, because of:\u2022 <span class=\"_ _29\"> </span>the business model identified for the management of financial assets (so-called \u201cBusiness Model\u201d);\u2022 <span class=\"_ _29\"> </span>the characteristics relating to the contractual cash flows of the financial asset, i.e., whether the cash flows generated by the financial asset consist solely of principal payments and accrued interest on the amount of principal to be repaid.  The Business Model for financial asset management determines whether cash flows will come from (i) the collection of cash under the contract, (ii) the sale of financial assets, or (iii) both.The test, aimed at determining whether the instrument generates cash flows representing solely payments of principal and interest (so-called \"Solely Payments of Principal and Interest\") and is referred to as the \"SPPI test\" and is performed at the individual instrument level.Financial assets \u2013 Subsequent measurementFinancial assets measured at amortised costFinancial assets at amortized cost mainly include trade receivables, other receivables, and financial receivables. Financial assets at amortized cost are held as part of a business model whose objective is to collect cash flows in accordance with contractual terms, represented exclusively by principal and interest on principal to be repaid at specific dates (so-called Hold T<span class=\"_ _0\"></span>o Collect business model).These assets, as indicated, are initially recognized at fair 8value, adjusted for transaction costs where appropriate, and subsequently measured at amortized cost using the effective interest rate.According to the amortised cost method the initial book value is then adjusted to account for repayments of principal, any impairments for credit losses and the amortisation of the difference between the repayment amount and the initial book value.Amortisation is carried out using the effective internal interest rate, which represents the rate that would make the present value of projected cash flows and the initial recognition value equal at the time of the initial recording.Financial assets valued at the amortised cost are presented in the statement of financial position net of the related 8 <span class=\"_ _48\"> </span>Except for trade receivables where, if they lack a significant financial component, they are initially recognized at transaction price (as defined in IFRS 15).provision for impairment losses.T<span class=\"_ _0\"></span>ransferred financial assets are derecognised from the balance sheet assets when the contractual rights to obtain the cash flows associated with the financial instrument expire, or all risks and rewards associated with the transferred receivable are transferred to a third party in accordance with the guidance on derecognition of financial assets set forth in IFRS 9.For financial assets measured at amortized cost, interest income determined on the basis of the effective interest rate, foreign exchange differences, and write-downs (including gains and losses from derecognition or modification of the asset) are recognized in the income statement.With specific reference to trade receivables, in order to measure Expected Credit Losses (\"ECLs\"), a valuation is made using the so-called \"simplified approach\" provided by IFRS 9, or - by virtue of the absence of a significant financial component - by estimating expected losses over the life of the receivable (\"lifetime ECLs<span class=\"_ _0\"></span>\").The assessment of the recoverability of trade receivables is made on both an individual and collective basis depending on the type of counterparty and whether there is reasonable and demonstrable information available to make an assessment at the individual instrument level.The group applies a specific definition of default, determined<span class=\"_ _4\"></span> by taking into account the characteristics of the operating segments to which the subsidiaries belong as well as the riskiness of the receivables and customers being assessed. Therefore, beyond the time limit of default, trade receivables<span class=\"_ _4\"></span> are assumed to be impaired (i.e. credit<span class=\"_ _0\"></span>-impaired).In particular<span class=\"_ _0\"></span>, expected losses are generally determined on the basis of the product between: (i) <span class=\"_ _16\"> </span>the amount of exposure to the counterparty at the time of default (so-called 'Exposure At Default' or 'EAD');(<span class=\"_ _4\"></span>ii<span class=\"_ _4\"></span>)<span class=\"_ _4\"></span> <span class=\"_ _8\"> </span>the probability that the counterparty will default on its<span class=\"_ _4\"></span> payment obligations (so-called Probability of Default or PD); (iii) the estimate, in percentage terms, of the amount of credit that will not be recovered in the event of default (so-called Loss Given Default or L<span class=\"_ _0\"></span>GD).With regard to the ECL parameters listed above, the group considers the following assumptions:(i) <span class=\"_ _16\"> </span>PD is determined according to the type of counterparty on the basis of:\u2022 <span class=\"_ _29\"> </span>qualified external providers (e.g. for listed companies);\u2022 <span class=\"_ _29\"> </span>regional ratings (e.g. for public administration<span class=\"_ _0\"></span>) by leading rating agencies;\u2022 <span class=\"_ _29\"> </span>average default rate calculated for groups of customers broken down by common credit risk (so-called 'cluster') considering historical data over a period of at least 24 months; (ii) <span class=\"_\"> </span>the LGD is obtained on the basis of market standards that assess the recovery rate of the exposure depending on the region and sector of the counterparty (e.g. corporate, government and retail);(iii) the E<span class=\"_ _4\"></span>AD is determined to be equal to the face value of the claim at the valuation date, less any related mitigating factor<span class=\"_ _0\"></span>, including any amounts pledged as collateral.In the case of credit exposures in litigation and where detailed information is available on the recoverability of the exposure, analytical assessments are performed in order to better reflect the actual riskiness of the position in the determination of expected losses. The exposures for which credit recovery actions have been activated through legal/court proceedings are defined as litigation.Impairments of trade receivables and other receivables are recognised in the income statement, net of any write-backs, under the item \u201cOther operating expenses\u201d.Financial assets, measured at fair value with effects recognized in other comprehensive income (FVTOCI) Credits and Debt Instrument<span class=\"_ _4\"></span>sIf present, financial assets representing loans and debt instruments whose business model envisages the possibility of both collecting the contractual cash flows and realizing their value through sale (so-called Hold to Collect and Sell, or Mixed, Business Model) are measured at fair value with the effects charged to OCI (so-called FV<span class=\"_ _4\"></span>TOCI). Under this measurement criterion, interest income, calculated using the effective interest rate, exchange rate differences and impairment losses are recognized in the income statement; changes in the fair value of the instrument are recognized in equity, among other components of comprehensive income.When a financial asset is derecognized (e.g., upon sale), the cumulative amount of changes in fair value, up to that point recognized in OCI, are reclassified to the income statement.The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\" - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Financial assets measured at fair value with effects charged to the income statementCredits and Debt Instrument<span class=\"_ _4\"></span>sThe category of financial assets measured at fair value through profit or loss (so-called FV<span class=\"_ _4\"></span>TPL) includes:\u2022 <span class=\"_ _29\"> </span>financial assets with cash flows that are not represented exclusively by principal and interest payments, regardless of the business model (financial assets that do not pass the SPPI test);\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets held for trading because they are </span>purchased or held primarily for the purpose of being sold (financial assets that pass SPPI test but held under a so-called Business Model T<span class=\"_ _0\"></span>rading)\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets for which the entity voluntarily adopts </span>the so-called Conditional F<span class=\"_ _0\"></span>air Value Option (these are<span class=\"_ _0\"></span> financial assets that pass the SPPI T<span class=\"_ _0\"></span>est and for which despite the Business Model being Hold to Collect or Mixed, the company decides to exercise the option<span class=\"_ _0\"></span> granted by IFRS 9 that allows the financial asset to be valued at FV<span class=\"_ _4\"></span>TPL).Where present, credits arising from invoice rebates to customers in the energy efficiency business (pertaining to so-called \"Ecobonus\" and \"Superbonus\") - and which<span class=\"_ _0\"></span> are converted into tax credits - if held with the objective of realizing cash flows through sale (so-called \"Other\" Business Model) are measured at fair value with the effects charged to the income statement (so-called FV<span class=\"_ _4\"></span>TPL).The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\"<span class=\"_ _0\"></span> - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Minority interestFinancial assets representing minority interests, which are not held for trading purposes, are measured at fair value alternatively with recognition of the effects: (i) in the income statement (so-called fair value measurement recognized in the income statement or FV<span class=\"_ _4\"></span>TPL) or in the equity reserve that holds the other components of comprehensive income, without provision for their reclassification to the income statement in the event of realization (so-called fair value measurement recognized in the statement of comprehensive income or FV<span class=\"_ _4\"></span>TOCI).This classification can be made on a security-by-security basis, only upon initial recognition, and is irrevocable.Dividends from such equity investments are recognized in the income statement under \"Income (expense) on equity investments,\" unless the dividend clearly represents a recovery of part of the cost of the investment; in which case the dividend is recognized as a direct reduction of the carrying amount of the equity investment<span class=\"_ _4\"></span>. Valuation<span class=\"_ _0\"></span> at cost of a minority investment is permitted in the limited cases where cost represents an adequate estimate of fair value.The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\"<span class=\"_ _0\"></span> - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Financial liabilitiesFinancial liabilities, unlike derivative instruments, including financial debt, trade payables and other payables, are initially recorded at fair value less any transaction- related costs; they are subsequently recognised at amortised cost using the effective interest rate for discounting purposes, as demonstrated in the previous point \"Financial assets valued at amortized cost\u201d.Financial liabilities are derecognized upon extinguishment or upon fulfilment, cancellation or maturity of the contractual obligation. Offsetting a financial asset and a financial liabilityFinancial assets and liabilities are offset in the statement of financial position when there is a currently legally enforceable right to set<span class=\"_ _0\"></span>-off and the intention either to settle the relationship on a net basis (i.e. to realise the asset and settle the liability simultaneously). Derivative financial instruments and hedge accountingDerivative financial instruments, including embedded derivatives, are assets and liabilities recognised at fair value. Under the scope of the strategy and objectives defined for risk management, the qualification of transactions as hedging requires: (i) the verification of the existence of an economic relationship between the object hedged and the hedging instrument for the purpose of offsetting the changes in value and ensuring this offsetting capacity is not invalidated by the level of counterparty credit risk; (ii) the definition of a hedge ratio consistent with the risk management objectives, under the scope of the risk management strategy defined, where necessary activating the appropriate rebalancing actions. The amendments of the risk management objectives, the disappearance of the conditions indicated previously for the qualification of transactions as hedging or the activation of rebalancing operations cause the total or partial prospective discontinuation of the hedge.In order to qualify a transaction as a hedge, at the start of the hedge a formal document is prepared that illustrates the strategies and objectives of the risk management and identifies the hedging instrument, the instrument hedged, the nature of the risk hedged and the methods through which the evaluation of whether the hedge relationship satisfies the hedge effectiveness requirements takes place.When hedging derivatives hedge the risk of changes in the fair value of the hedged instruments (\u201cfair value hedge\u201d; e.g. hedge of the risk of fluctuations in the fair value of fixed-rate assets/liabilities), the derivatives are recognised<span class=\"_ _0\"></span> at fair value with attribution of the effects on the income statement; by the same token, the hedged instruments are adjusted to reflect in the income statement the changes in fair value associated with the hedged risk, regardless of the provision of a different valuation criterion generally applicable to the instrument type.The group subscribes to derivative instruments to cover the risk of changes in cash flows (cash flow hedges) as a result of fluctuations in interest rate or exchange rates. Changes in the fair value of hedging derivatives considered effective are initially recognised in the shareholders\u2019 equity reserve relating to other components in the comprehensive income statement and are subsequently reclassified to profit or loss in line with the economic effects produced by the hedged transaction. In the case of hedging future transactions that involve the recording of a non-financial asset or liability, the cumulative variations of the fair value of the hedge derivatives, recognised in shareholders\u2019 equity, are recognised in the adjustment of the book value of the non- financial asset/liability subject to hedging (basis adjustment).The ineffective portion of the hedge and the changes in the fair value of derivatives that do not meet the qualifying conditions for hedging are recognised in the income statement.<span class=\"ls0\"> </span>T<span class=\"_ _3\"></span>reasury sharesT<span class=\"_ _0\"></span>reasury shares, including those held to ser<span class=\"_ _4\"></span>vice share-based payment plans (share incentive plans), are measured at cost and entered as a reduction of shareholders\u2019 equity. The economic effects arising from any subsequent sales are recognised in shareholders\u2019 equity.Distribution of dividendsThe distribution of dividends to the Company\u2019s shareholders entails the recording of a payable in the financial statements for the period in which distribution was approved by the Company\u2019s shareholders or<span class=\"_ _0\"></span>, in the case of interim dividends, by the Board of Directors.5.8 <span class=\"_ _82\"> </span>Fair value measurementThe fair value is the amount that may be received for the sale of an asset or that may be paid for the transfer of a liability in a regular transaction between market<span class=\"_ _0\"></span> operators as at the valuation date (i.e. exit price).The fair value of an asset or liability is determined by adopting the valuations that market operators would<span class=\"_ _0\"></span> use to determine the price of the asset or liability. A<span class=\"_ _0\"></span> fair value measurement also assumes that the asset or liability would be traded on the main market or<span class=\"_ _3\"></span>, failing that, on the most advantageous market to which the Company has access.The fair value of a non-financial asset is determined by considering the capacity of market operators to<span class=\"_ _0\"></span> generate economic benefits by putting the asset to its maximum and best use or by selling it to another market participant capable of using it in such a way as<span class=\"_ _0\"></span> to maximise its value. The maximum and best use of an asset is determined from the perspective of market<span class=\"_ _0\"></span> operators, also hypothesising that the company intends<span class=\"_ _0\"></span> to put it to a different use; the current use by the company of a non-financial asset is assumed to be the maximum and best use of this asset, unless the market or other factors suggest that a different use by market<span class=\"_ _0\"></span> operators would maximise its value.The fair-value measurement of a financial or non-financial liability, or of an equity instrument, takes<span class=\"_ _0\"></span> into account the quoted price for the transfer of an identical or similar liability or equity instrument; if this quoted price is not available, the valuation of a corresponding asset held by a market operator as at<span class=\"_ _0\"></span> the valuation date is taken into account. The fair value of financial instruments considers the credit risk of the counterparty for financial assets (through a \u201cCredit<span class=\"_ _0\"></span> Valuation Adjustment\u201d - CV<span class=\"_ _0\"></span>A) and the entity\u2019s own risk of default for financial liabilities (through a \u201cDebit Valuation<span class=\"_ _0\"></span> Adjustment\u201d - DV<span class=\"_ _3\"></span>A).When determining fair value, a hierarchy is set out<span class=\"_ _0\"></span> consisting of criteria based on the origin, type and quality of the information used in the calculation. This classification aims to establish a hierarchy in terms of the<span class=\"_ _0\"></span> reliability of the fair value, giving precedence to the use of parameters that can be observed on the market and that reflect the assumptions that market participants<span class=\"_ _0\"></span> would use when valuing the asset/liability.<span class=\"_ _0\"></span> The fair value hierarchy includes the following levels:\u2022 <span class=\"_ _29\"> </span>level 1: listed prices (unadjusted) in active mark<span class=\"_ _0\"></span>ets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;\u2022 <span class=\"_ _29\"> </span>level 2: inputs, other than the quoted prices included in Level 1, that can be directly or indirectly observed for the assets or liabilities to be valued;\u2022 <span class=\"_ _29\"> </span>level 3: inputs for assets or liabilities that are not based on observable market data.In the absence of available market quotations, the fair value is determined by using valuation techniques suitable for each individual case that maximise the use of significant observable inputs, whilst minimising the use of non-observable inputs.5.9 <span class=\"_ _82\"> </span>Provision for risks and charges,  <span class=\"_ _70\"> </span>contingent liabilities and contingent assetsProvisions for risks and charges concern costs and charges of a certain nature which are certain or likely to be incurred, but for which the amount or date of occurrence cannot be determined at the end of the year<span class=\"_ _0\"></span>.The provisions are recognised when: (i) the existence of a current legal or implied obligation arising from a past event is probable; (ii) it is probable that the fulfilment of the obligation will involve a cost; and (iii) the amount of the obligation can be reliably determined. Provisions are recorded at the value representing the best estimate of the amount that the Company would reasonably pay to fulfil the obligation or to transfer it to third parties at the end of the reporting period.Provisions related to contracts with valuable consideration are recorded at the lower of the cost necessary to fulfil the obligation, less the expected economic benefits arising from the contract, and the cost of terminating the contract.When the financial impact of time is significant, and the payment dates of the obligations can be reliably estimated, the provision is calculated by discounting the anticipated cash flows in consideration of the risks associated with the obligation at the Company\u2019s average debt rate; the increase in the provision due to the passing of time is posted to the income statement under \u201cFinancial income (expense)\u201d.When the liability is related to items of property, plant and equipment (e.g. decommissioning and site restoration), the provision is recognised as a counter-entry to the related asset, and posting to the income statement is accomplished through amortisation. The costs that the Company expects to incur to initiate restructuring programmes are recorded in the period in which the programme is formally defined, and the parties concerned have a valid expectation that the restructuring will take place.Provisions are periodically updated to reflect changes in cost estimates, selling periods and the discount rate; revisions in provision estimates are allocated to the same item of the income statement where the provision was previously reported or<span class=\"_ _0\"></span>, when the liability is related to property, plant and equipment (e.g. site dismantling and restoration), as a contra-entry to the related asset, up to the book value; any surplus is posted to the income statement.The notes to the financial statements describe contingent liabilities represented by: (i) possible (but not probable) obligations resulting from past events, the existence of which will be confirmed only if one or more future uncertain events occur which are partially or fully outside the Company\u2019s control; and (ii) current obligations resulting from past events, the amount of which cannot be reliably estimated, or the fulfilment of which is not likely to involve costs.Contingent assets, or possible assets that result from past events and whose existence will only be confirmed when one or more uncertain future events, not totally under the control of the business, occur or do not occur<span class=\"_ _0\"></span>, are not recognised unless obtaining the related benefits is virtually certain. If obtaining the benefits is probable, the contingent assets are illustrated in the notes to the financial statements.5.10 <span class=\"_ _34\"> </span>Non-current assets held for sale  and discontinued operationsNon-current assets or disposal groups consisting of assets and liabilities are classified as held for sale if their book value will be recovered mainly by their sale rather than through continued use. This condition is regarded as fulfilled when the sale is highly probable and the asset or discontinued operations are available for immediate sale in their current condition. In the case of a programme for the sale of a subsidiary that results in loss of control, all assets and liabilities of that subsidiary are classified as held for sale, regardless of whether a non-controlling investment is maintained following the sale. V<span class=\"_ _0\"></span>erification of compliance with the terms and conditions provided for classification of an item as held for sale requires management to make subjective valuations formulating reasonable and realistic assumptions based on the information available to it. Immediately prior to classification as held for sale, the assets and liabilities included in a disposal group are measured in accordance with the accounting standards applicable to them. Subsequently, non- current assets held for sale are not amortised or depreciated and are measured at the lower of book value and related fair value, less any sales costs (see paragraph 5.8 \u201cF<span class=\"_ _0\"></span>air<span class=\"_ _0\"></span>-value measurements\u201d above).The classification of investments accounted for using the equity method as held for sale implies the suspension of the application of this valuation criterion. Any negative difference between the book value of the non-current assets and their fair value less selling costs is posted to the income statement as an impairment loss; any subsequent recoveries in value are recognised up to the amount of the previously recognised impairment losses, including those recognised prior to the asset being classified as held for sale.Non-current assets and disposal group- related assets and liabilities held for sale are recognised in the statement of financial position separately from the group\u2019s other assets and liabilities.Non-current assets and disposal groups, classified as held for sale, constitute a discontinued operation if<span class=\"_ _0\"></span>, alternatively:  (i) <span class=\"_ _16\"> </span>they represent a significant autonomous business unit or a significant geographical area of operations; (ii) <span class=\"_\"> </span>they are part of a plan to dispose of a significant autonomous business unit or a significant geographical area of operations;  (iii) they relate to a subsidiar<span class=\"_ _4\"></span>y acquired exclusively to be sold. The economic results of discontinued operations, as well as any capital gains/losses realised on the disposal, are recorded separately in the Income Statement under a special item, net of related tax effects, including for the comparative periods.When events occur that no longer permit non-current assets or disposal groups to be classified as held for sale, they are reclassified to the respective items in the statement of financial position and recognised at the lower of the following: (i) the book value at the date of classification as held for sale; and (ii) the recoverable amount at the reclassification date.5.1<span class=\"_ _3\"></span>1 RevenueThe recognition of revenue from contracts with customers is based on the following five steps: (i) identification of the contract with the customer; (ii) identification of the performance obligation, represented by the contractual commitment to transfer goods and/or services to a customer; (iii) calculating of the transaction\u2019s price; (iv) allocating of the transaction price to the performance obligations identified based on the stand alone sales price of each of the goods or services; (v) measuring the revenue when the performance obligation is met, i.e. at the time of the transfer to the customer of the goods or services promised; the transfer is considered to be completed when the customer obtains control of the goods or service, which can take place over time or at a point in time.Revenues are measured for the amount equal to the fair value of the consideration which the business believes it has the right to in exchange for the goods and/or services promised to the customer<span class=\"_ _0\"></span>, with the exception of amounts collected on behalf of third-parties. If there is a variable consideration, the business estimates the amount of the consideration it shall have the right to in exchange for the transfer of goods and/or services promised to the customer;<span class=\"_ _4\"></span> specifically, the amount of the consideration can vary in the presence of discounts, incentives, concessions on the price, performance bonuses, penalties or if the actual price depends on certain future events taking place or not.Revenues from the Snam Group\u2019s ordinary operations mainly consist of services relating to the transportation, dispatching and storage of natural gas and the regasification of liquefied natural gas, which are recognised in the financial statements over the period in which the service is provided, whether the ser<span class=\"_ _4\"></span>vices are \u201cregulated\u201d or \u201cnon-regulated\u201d. The recognition of revenues for regulated services is conditioned and influenced by the regulatory framework defined by ARER<span class=\"_ _4\"></span>A (Autorit\u00e0 di Regolazione per Energia Reti e Ambiente \u2013 Regulatory Authority for Energy Networks and the Environment). Therefore, the economic conditions of the services provided are defined through regulator<span class=\"_ _4\"></span>y schemes and not on a negotiated basis. The revenue recognised in the income statement coincides with that recognised by the regulator (so-called \u201crevenue cap\u201d). As regards the transportation business segment, the difference between the revenue recognised by the regulator (so- called \u201crevenue cap\u201d) and that actually accrued is recorded, if positive, in the item of the statement of financial position \u201cTrade payables and other payables\u201d and, in the item \u201cTrade and other payables\u201d, as it will be subject to cash settlement with the Cassa per i Servizi Energetici e Ambientali (CSEA). In the Regasification and Storage segments any difference between the revenue recognised by the regulator and the accrued revenue is recognised in the balance sheet item \u201cTrade and other receivables\u201d, if positive, and in the item \u201cTrade payables and other payables\u201d, if negative, inasmuch as it will be subject to cash settlement with the Energy and Environmental Services Fund (CSEA).Non-regulated revenues mainly involve: (i) considerations for the construction of biogas and biomethane plants; (ii) technical- specialist services to unconsolidated foreign companies; (iii) the provision of services relating to energy efficiency projects; (iv) income from the rental and maintenance of fibre optic telecommunication cables; (v) the sale of CNG compressors for motor transport. The recognition of these revenues takes place over the service provision period.By virtue of the principle of neutrality defined by applicable regulations, transactions carried out on the balancing market generate neither costs nor revenue, as they are mere pass-through items. Any (positive or negative) differences from the usage of different prices for the transactions above will be neutralized by recognizing an asset or liability for CSEA<span class=\"_ _4\"></span>, given that these differences are equalized by the latter<span class=\"_ _0\"></span>. 5.12 <span class=\"_ _34\"> </span>Employee benefitsShort-term benefits for employeesShort<span class=\"_ _0\"></span>-term benefits for employee are recognised as a cost at the time when the service is rendered. The Group recognises a liability, classified under \u201cTrade payables and<span class=\"_ _0\"></span> other payables\u201d for the amount due to be paid when it has a current legal or constructive obligation to make such payments.<span class=\"ls0 ws0\"> </span>Post-employment benefitsPost<span class=\"_ _0\"></span>-employment benefits are defined according to programmes, including non- formalised programmes, which, depending on their characteristics, are classed as \u201cdefined-benefit\u201d or \u201cdefined-contribution\u201d plans.\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\"> Defined-benefit plansi</span>The liability associated with defined-benefit plans is determined by estimating the present value of the future benefits accrued by the employees during the current year and in previous years, and by calculating the fair value of any assets servicing the plan. The present value of the obligations is determined based on actuarial assumptions and is recognised on an accruals basis consistent with the employment period necessary to obtain the benefits.Actuarial gains and losses relating to defined-benefit plans arising from changes in actuarial assumptions or experience adjustments are recognised in the comprehensive income statement in the period in which they occurred,and are not subsequently recognised in the income statement. When a plan changed, reduced or extinguished, the relative effects are recognised in the income statement.Net financial expense represents the change that the net liability undergoes during the year due to the passing of time. Net interest is determined by applying to the liabilities, net of any plan assets, the discount rate used for the discounting used for the liabilities. The net financial expense of defined-benefit plans is recognised in \u201cFinance expense (income)\u201d.\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Defined-contribution plans</span>In defined-contribution plans, the Company\u2019s obligation is calculated, limited to the payment of state contributions or to equity or a legally separate entity (fund), based on contributions due. The costs associated with defined-benefit contributions are recognised in the income statement as and when they are incurred.Other long-term benefitsObligations relating to other long-term benefits are calculated using actuarial assumptions; the effects arising from the amendments to the actuarial assumptions or the characteristics of the benefits are recognised entirely in the income statement. Benefits payable on termination of employmentThe benefits payable to employees for termination of employment are recognised as an expense when the Company is committed to offering the benefits and has no option to withdraw them, or<span class=\"_ _0\"></span>, if earlier<span class=\"_ _3\"></span>, when the company recorded restructuring costs. Share-based payments (Share-based incentive plan)Employee benefits, consistent with the essential nature of the remuneration that they comprise, include the cost of share-based incentive plans. The incentive cost is calculated with reference to the fair value of the instruments allocated and the forecast of the number of share that will effectively be allocated; the share pertaining to the financial year is calculated pro-rata temporis throughout the vesting period, or the period between the grant date and the allocation date. The fair value of the shares underlying the incentive plan is calculated at the grant date taking into account the forecasts with regard to reaching the performance parameters associated with market conditions and is not adjusted in future financial years; when obtaining the benefit is also connected to conditions other than market conditions, the estimate relating to these conditions is reflected by adjusting the number of shares during the vesting period that are expected to effectively be allocated.5.13 <span class=\"_ _34\"> </span>Accounting for environmental  certificates - Emission trading  systemsThe European Emission T<span class=\"_ _0\"></span>rading System, established to manage and trade emission allowances, sets an upper limit for greenhouse gas emissions produced over the course of a year<span class=\"_ _0\"></span>, for which a certain number of emission allowances are issued free of charge by the competent national authorities. Depending on the actual greenhouse gas emissions produced during the year<span class=\"_ _0\"></span>, each company is entitled to sell or is obliged to buy emission allowances on the market.Allowances purchased for a consideration to offset emissions released into the atmosphere during the year are recognised in the income statement; any allowances purchased beyond what is necessary are recognised in \u201cOther current assets\u201d.Any allowances allocated free of charge and not used in the year of allocation are not recognised in the financial statements as they are used for the following year\u2019s requirements.If there is a deficit for emission allowances that have not been purchased on the market at the balance sheet date, the cost and corresponding liability are recognised at market value at the end of the financial year<span class=\"_ _3\"></span>.5.14 <span class=\"_ _34\"> </span>Foreign currency transactionsThe criteria adopted by Snam to convert transactions in currencies other than the functional currency (the Euro) are summarised below:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">revenue and costs relating to transactions in currencies </span>other than the functional currency are recognised at the exchange rate in effect on the day when the transaction was carried out;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">monetar<span class=\"_ _4\"></span>y assets and liabilities in currencies other than </span>the functional currency are converted into Euro by applying the exchange rate in effect on the reporting date, allocating the effect to the income statement;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">non-monetar<span class=\"_ _4\"></span>y assets and liabilities in currencies other </span>than the functional currency which are valued at cost are recognised at the initially recorded exchange rate; when the measurement is made at fair value or recoverable or realisable value, the exchange rate used is the one in effect on the valuation date.5.15 <span class=\"_ _34\"> </span>Income taxesCurrent income taxes are calculated by estimating<span class=\"_ _0\"></span> the taxable income. T<span class=\"_ _0\"></span>ax payables and receivables for current taxes are recognised at the value of the current tax liability that are expected to be paid/recovered to/from the tax authorities by applying the tax rates and regulations in force or substantially approved at the end of the financial year<span class=\"_ _0\"></span>. Regarding corporation tax (IRES), Snam has exercised the option to join the national tax consolidation scheme, to which all the consolidated companies have officially signed up, except for Mieci S.p.<span class=\"_ _4\"></span>A., Evolve S.p.<span class=\"_ _4\"></span>A<span class=\"_ _4\"></span>. and T<span class=\"_ _0\"></span>-lux S.r<span class=\"_ _0\"></span>.l.

The taxable income of the subsidiary, used to determine the tax, is adjusted to account for the recovery of negative components that would have been non-deductible without the consolidation scheme (e.g. interest expense), the so-called ACE (help for economic growth) effect and an<span class=\"_ _0\"></span>y negative taxable income relating to the subsidiary<span class=\"_ _4\"></span>\u2019s equity investments in consolidated companies;\u2022 <span class=\"_ _29\"> </span>subsidiaries with negative taxable income, if and insofar as they have prospective profitability which, without the national tax consolidation scheme, would have enabled them to recognise deferred tax assets related to the negative taxable income on the separate financial statements, receive from their shareholders \u2013 in the event that these are companies with a positive taxable income or a negative taxable income with prospective profitability \u2013 or from Snam in other cases, compensation amounting to the lower of the tax saving realised by the Group and the aforementioned deferred tax assets.Regional production tax (IR<span class=\"_ _4\"></span>AP<span class=\"_ _0\"></span>) is recognised under the item \u201cCurrent tax liabilities\u201d/\u201c<span class=\"_ _0\"></span>Current tax assets\u201d.Deferred taxes are calculated on the timing differences between the values of the assets and liabilities entered in the balance sheet and the corresponding values recognized for tax purposes, based on the prevailing tax regulations and rates applicable in financial years in which the temporary difference will be cancelled, approved or essentially approved at the end closing date of the reference year of the financial statements. Deferred tax assets are recognised when their recovery is considered probable; specifically, the recoverability of deferred tax assets is considered probable when taxable income is expected to be available in the period in which the temporary difference is cancelled, allowing the activation of the tax deduction. Similarly, unused tax credits and deferred tax assets on tax losses are recognised within the limits of their recoverability; with reference to deferred tax assets, their recoverability is verified at least annually.If there are uncertainties over the application of tax regulations: (i) in cases where it is deemed probable that the tax authorities will accept the uncertain tax treatment, the income taxes (current and/or deferred) to be recognised in the financial statements according to the tax treatment applied or which it is expected to apply during the tax return are calculated; (ii) in cases where it is not deemed probable that the tax authorities will accept the uncertain tax treatment, this uncertainty is reflected in calculating the (current and/or deferred) income taxes to be recognised in the financial statements.Deferred tax assets and deferred tax liabilities are classified under non-current assets and liabilities and are offset at individual company level if they refer to taxes which can be offset and/or at the level of the consolidating company in the presence of the taxation regime set out in the national consolidation scheme. The balance of the offsetting, if it results in an asset, is recognised under the item \u201cDeferred tax assets\u201d; if it results in a liability, it is recognised under the item \u201cDeferred tax liabilities\u201d. When the results of transactions are recognised directly in equity, current and deferred taxes are also posted to equity.5.16 <span class=\"_ _34\"> </span>Segment reporting  (operating segments)Disclosure on business segments has been prepared pursuant to IFRS 8 \u2013 \u201cOperating Segments\u201d:consequently, the identification of the operating segments and the information presented are defined on the basis of the internal reporting used by the Company\u2019s management to allocate resources to the different segments and to analyse the respective performances.An operating segment is defined by IFRS 8 as the component of<span class=\"_ _4\"></span> an entity that: (i) that engages in business activities from which<span class=\"_ _4\"></span> it may earn revenue and incur expenses (including revenue and<span class=\"_ _4\"></span> expenses relating to transactions with other components of the<span class=\"_ _4\"></span> same entity); (ii) for which the operating results are regularly<span class=\"_ _4\"></span> reviewed by the entity\u2019s most senior decision-makers for the purpose of making decisions about resources to be allocated to<span class=\"_ _4\"></span> the segment and assessing its performance; and (iii) for which<span class=\"_ _4\"></span> separate financial information is available.With reference to the financial year 2022, the business segments subject to reporting under IFRS 8 are: (i) the T<span class=\"_ _0\"></span>ransportation segment, relating to natural gas transportation<span class=\"_ _4\"></span> activities; (ii) the Regasification segment, relating to Liquefied<span class=\"_ _4\"></span> Natural Gas regasification activities; (iii) the Storage segment,<span class=\"_ _4\"></span> relating to natural gas storage activities; (iv) the Energy transition segment, relating to energy efficiency, biogas/biomethane business and hydrogen start<span class=\"_ _0\"></span>-up projects. The Mobility segment, together with the activities of Snam Global solution, do not constitute operating segments subject to separate reporting under IFRS 8. The relevant values are shown in the aggregate \"Other segments\". 6ASSUMPTIONS AND<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>UNCERT<span class=\"_ _32\"></span>AINTIES IN ESTIMA<span class=\"_ _3\"></span>TES  The application of generally accepted accounting principles for the preparation of financial statements involves management making accounting estimates based on complex and/or subjective judgements, estimates based on past experience and assumptions regarded as reasonable and realistic on the basis of the information known at the time of the estimate. The use of these accounting estimates has an influence on the book value of the assets and liabilities and on the information about potential assets and liabilities at the reporting date, as well as the amount of revenue and costs in the reference period. The actual results may differ from the estimated results owing to the uncertainty that characterises the assumptions and the conditions on which the estimates are based. Details are given below about the critical accounting estimates involved in the process of preparing the financial statements and interim reports, since they involve a high degree of recourse to subjective judgements, assumptions and estimates regarding matters that are by nature uncertain. Any change in the conditions forming the basis of the judgements, assumptions and estimates used could have a significant impact on subsequent results.6.1 <span class=\"_ _82\"> </span>Impairment of non-financial assetsNon-financial assets are impaired when events or changes in circumstances give cause to believe that the book value is not recoverable. The events that can lead to an impairment of assets include changes in business plans, changes in market prices or reduced use of plants. The decision on whether to apply an impairment and the quantification of any such impairment depend on the Company\u2019s management assessment of complex and highly uncertain factors, such as future price trends, the impact of inflation and technological improvements on production costs, production profiles and conditions of supply and demand. The impairment is determined by comparing the book value with the related recoverable value, represented by the greater of the fair value, net of disposal costs, and the usage value, determined by discounting the expected cash flows deriving from the use of the asset, or represented by the R<span class=\"_ _4\"></span>AB in the regulated business segments. The expected cash flows are quantified in the light of the information available at the time of the estimate, on the basis of subjective judgements regarding future trends in variables \u2013 such as prices, costs, the rate of growth of demand and production profiles \u2013 and are discounted using a rate that takes account of the risk inherent to the asset concerned. The rationale behind the impairment testing used by management in relation to property plant and machinery, intangible assets, goodwill and investments<span class=\"_ _4\"></span> accounted for using the equity method are illustrated respectively in note 8 \u201c\u2018Property, plant and equipment\u2019\u201d, note 9 \u201c\u2018Intangible assets and goodwill\u201d and note 10 \u201cInvestments accounted for using the equity method\u201d.6.2 <span class=\"_ _82\"> </span>Impairment of financial assetsAt each reporting date, assessments are made of the recoverability of financial assets in order to determine the value of expected credit losses (ECL).In particular<span class=\"_ _0\"></span>, the valuation of trade receivables is carried out using the simplified approach established by IFRS 9, which involves estimating the ECL over the life of the receivable. In these cases, the impairment is generally based on the expected credit loss model and is carried out through the use of both qualified external providers and by means of an analysis of observed historical data with respect to credit recoverability; analysis performed for homogeneous categories of counterparties. On the other hand, for certain categories of credits characterised by peculiar risk elements (e.g. litigation or credit recovery practices through legal/judicial proceedings), specific assessments are carried out on individual credit positions. The logic behind the expected credit loss model is explained in Note 5 \"Significant accounting standards\" - \"Non-derivative Financial Assets -Receivables and Debt securities\", respectively.6.3 <span class=\"_ _82\"> </span>Provisions for risks and charges  Provision for decommissioning and site restorationThe Snam Group incurs significant liabilities associated with obligations to remove and dismantle plants or parts of plants. Estimating future dismantling and restoration costs is a complex process and requires the assessment and judgement of the Company\u2019s management in placing a value on the liabilities that will be incurred many years in the future for compliance with dismantling and restoration obligations, which often cannot be fully defined by laws, administrative regulations or contractual clauses. In addition, these obligations are affected by constant changes in technology and in dismantling and restoration costs, as well as the constant growth of political and public awareness regarding matters of health and protection of the environment.The criticality of estimates of dismantlement and restoration costs also depends on the accounting method used for these costs, for which the current value is initially capitalised together with the cost of the asset to which they relate, offset against the provision for risks and charges. Thereafter<span class=\"_ _0\"></span>, the value of the provision for risks is updated to reflect the passing of time and any changes in the estimate as a result of changes in expected cash flows, the timing of their realisation and the discount rates applied.The calculation of the discount rate to be used both in the initial valuation of the cost and in subsequent valuations is the result of a complex process which involves subjective judgements on the part of the Company\u2019s management. Environmental liabilitiesThe Snam Group is subject, in relation to its activities, to numerous laws and regulations on environmental protection at European, national, regional and local level, including the laws which implement international conventions and protocols relating to the activities carried out. With reference to this legislation, when it is probable that the existence and amount of a large liability can be reliably estimated, provisions are made for the associated costs.The group does not currently believe that the financial statements will suffer particularly significant adverse effects due to non-compliance with environmental regulations, also considering actions already undertaken, but it cannot be ruled out with certainty that Snam may incur further<span class=\"_ _0\"></span>, possibly significant, costs or liabilities, since current knowledge says it is impossible to predict the effects of future developments, taking into account also the following aspects: (i) the possible emergence of contamination; (ii) the outcome of the refurbishment in progress and to be followed and the other possible effects arising from the application of the laws in force; (iii) the possible effects of new laws and regulations for environmental protection; (iv) the effects of any technological innovations for environmental reclamation; (v) the possibility of disputes and the difficulty of determining the possible consequences, also in relation to the liability of other parties and to possible compensation payments.Provisions for legal and tax disputesThe estimation of the group\u2019s provisions for these purposes is the result of a complex process involving subjective judgements by Company management.6.4 <span class=\"_ _82\"> </span>Investments and business  combinationsV<span class=\"_ _0\"></span>erification of the existence of control, joint control, considerable influence over another entity as well as, in the case of joint operations, verification of the existence of enforceable rights and obligations requires Corporate Management to exercise professional judgement taking into consideration the characteristics of the corporate structure and agreements between the parties as well as other facts and circumstances that are relevant for the purpose of this check. Similar considerations also apply in cases of a planned change in status following a loss of control, joint control or connection with the possible need to activate the classification as \u201cassets held for sale/discontinued operation\u201d.The reporting of business combination transactions involves the allocation to the assets and liabilities of the acquired company of the difference between the acquisition cost and the net book value. For the majority of assets and liabilities, the attribution of the difference is carried out by recognising the assets and liabilities at their fair value. The unallocated portion, if positive, is recognised as goodwill; if negative, it is allocated to the income statement. In the allocation process, the Snam Group draws on the available information and, for the most significant business combinations, on external valuations.6.5 <span class=\"_ _82\"> </span>Employee benefitsDefined-benefit plans are valued on the basis of uncertain events and actuarial assumptions which include, inter alia, the discount rates, the expected returns on the assets servicing the plans (where they exist), the level of future remuneration, mortality rates, the retirement age and future trends in the healthcare expenses covered.The main assumptions used to quantify defined-benefit plans are determined as follows: (i) the discount and inflation rates representing the base rates at which the obligation to employees might actually be fulfilled are based on the rates which mature on high-quality bonds and on inflation expectations; (ii) the level of future remuneration is determined on the basis of elements such as inflation expectations, productivity, career advancement and seniority; (iii) the future cost of healthcare services is determined on the basis of elements such as present and past trends in healthcare costs, including assumptions regarding the inflationary growth of costs, and changes in the health of the participating employees; and (iv) the demographic assumptions reflect the best estimates of trends in variables such as mortality, turnover<span class=\"_ _3\"></span>, invalidity and others in relation to the population of the participating employees.Differences in the value of net liabilities (assets) in employee benefit plans, arising due to changes in the actuarial assumptions used and the difference between the actuarial assumptions previously adopted and actual events, occur routinely and are called actuarial gains and losses. Actuarial gains and losses relating to defined-benefit plans are recognised in the comprehensive income statement. Actuarial assumptions are also used to determine obligations relating to other long-term benefits; to this end, the effects arising from changes to the actuarial assumptions or the characteristics of the ben<span class=\"_ _4\"></span>efit are fully recognised in the income statement.6.6 <span class=\"_ _82\"> </span>Fair valueCalculating the fair value of financial and non-financial instruments is a structured process featuring the use of complex evaluation methodologies and techniques that involve collecting up to date information from the reference markets and/or using internal input data.Similar to other estimates, calculating the fair value, albeit based on the best information available and on the adoption on adequate evaluation methodologies and techniques, it intrinsically features random elements and the exercising of professional judgement and could create forecasts with different values from those that will effectively be realised.6.7 <span class=\"_ _82\"> </span>Classification and measurement  of investments made for development<span class=\"_ _4\"></span>  <span class=\"_ _70\"> </span>and maintenance of proprietary  infrastructuresThe Snam Group makes significant investments for development and maintenance of its own infrastructures. Assessing the recoverability of the investments currently underway and the distinction of the costs as improvements, upgrades and transformations that increase the infrastructure and the expenses for ordinary maintenance and repairs which restore but do not increase the performance of the assets, includes valuation elements. These assessments are formulated on the basis of objective criteria that the Group has developed to facilitate an application consistent with its accounting policies.7ACCOUNTING ST<span class=\"_ _1\"></span>ANDARDS <span class=\"ls0 ws0\"> </span>PUBLISHED BY<span class=\"_ _3\"></span> THE IASB<span class=\"_ _0\"></span> BUT NOT<span class=\"_ _0\"></span> YET ENTERED<span class=\"_ _0\"></span> INT<span class=\"_ _0\"></span>O FORCE<span class=\"_ _0\"></span> New accounting standards or amendments to existing accounting standards issued by the IASB with an effective date after 31 December 2022 are set out below. The<span class=\"_ _0\"></span> new accounting standards or amendments to current accounting standards shown below are divided between documents that have been approved and those that have not yet been approved by the European Commission.7.1 <span class=\"_ _82\"> </span>Accounting standards  <span class=\"_ _70\"> </span>published by the IASB and  <span class=\"_ _70\"> </span>approved by the European  <span class=\"_ _70\"> </span>Commission but not yet  <span class=\"_ _70\"> </span>entered into force  \u2022 <span class=\"_ _48\"> </span>Regulation no. 2021/2036 issued by the European Commission on 19 November 2021 endorsed the regulatory provisions contained in<span class=\"ff63\"> IFRS 17 \u201cInsurance </span>Contracts\u201d<span class=\"ff6f ws0\">, issued by the IASB on 18 May 2017. The </span>document applies to all insurance contracts and defines the principles of recognition, measurement, presentation and disclosure, replacing IFRS 4. The new standard requires a \u201cBuilding Block Approach\u201d (BBA)<span class=\"_ _0\"></span> based on expected cash flow and the specification of a \u201crisk adjustment\u201d and of a Contractual Service Margin (CSM) which represents expected profit from insurance contract. This margin is reported in the income statement in the period in which the insurance cover is provided. Moreover<span class=\"_ _0\"></span>, there are two alternative approaches in addition to the BBA which are the \u201cVariable Fee Approach\u201d (VF<span class=\"_ _0\"></span>A) and the Premium Allocation Approach (P<span class=\"_ _0\"></span>AA), applicable in specific cases. The standard also provides for a new method of presentation in the income statement, which presents the following separately: (i) \u201cinsurance revenues\u201d, (ii) \u201cinsurance service expenses\u201d and (iii) \u201cinsurance finance income or expenses\u201d. <span class=\"_ _8b\"> </span>The provisions contained in IFRS 17 are effective from financial years starting on or after 1 January 2023, and the directors are evaluating the possible effects associated with its introduction; however<span class=\"_ _0\"></span>, at the moment, it is reasonable to believe that the first application of these changes will not have a significant impact on the financial statements, also in light of the policy choices and exemptions allowed by the standard with reference to \u2018Insurance contracts issued to subsidiaries, associates and joint ventures\u2019.\u2022 <span class=\"_ _48\"> </span>Regulation No. 2022/357, issued by the European Commission on 2 March 2022, endorsed the regulatory provisions contained in the documents (i) \"<span class=\"ff63 ws14\">Disclosure </span>of Accounting P<span class=\"_ _0\"></span>olicies-Amendments to IAS 1 and IFRS Practice Statement 2<span class=\"ff6f\">\" and (ii) \"</span>Definition of Accounting Estimat<span class=\"_ _0\"></span>es-Amendments to IAS 8<span class=\"ff6f ls0\">\", </span>amendments published by the IASB on 12 Februar<span class=\"_ _4\"></span>y 2021. The amendments are intended to improve the disclosure of accounting policies so as to provide more useful information to investors and other primary users of financial statements and to help companies distinguish changes in accounting estimates from changes in accounting policies. The amendments will apply from 1 January 2023. However, earlier<span class=\"_ _0\"></span> application is permitted. \u2022 <span class=\"_ _48\"> </span>By Regulation no. 2022/1392, issued by the European Commission on 11 August 2022, the regulatory provisions were approved as contained in the document \"<span class=\"ff63\">Amendments to IAS 12 Income T<span class=\"_ _0\"></span>ax<span class=\"_ _0\"></span>es: </span>Deferred T<span class=\"_ _0\"></span>ax related t<span class=\"_ _0\"></span>o Assets and Liabilities arising from a Single T<span class=\"_ _0\"></span>ransaction<span class=\"ff6f\">\",  amendment published by </span>the IASB on 7 May 2021. The document clarifies how deferred taxes should be accounted for on certain transactions that may generate assets and liabilities of equal amounts, such as leases and decommissioning obligations. The amendments will apply from 1 January 2023.\u2022 <span class=\"_ _48\"> </span>By Regulation no. 2022/1491, issued by the European Commission on 08 September 2022, the regulatory provisions were approved as contained in the document (i)\"<span class=\"ff63\">Amendments to IFRS 17 Insurance </span>contracts: Initial Application of IFRS 17 and IFRS 9 - Comparative Inf<span class=\"_ _0\"></span>ormation<span class=\"ff6f\">\", amendment published </span>by the IASB on 9 December 2021. The amendment is a transition option relating to comparative information about financial assets presented at the date of initial application of IFRS 17. The amendment is intended to avoid temporary accounting mismatches between financial assets and liabilities of insurance contracts, and thus to improve the usefulness of comparative information for readers of financial statements. The amendments will apply from 1 January 2023, together with the application of IFRS 17.  The Group is analysing the standards and interpretations indicated, where applicable, in order to assess the effects of their application on the financial statements. However<span class=\"_ _0\"></span>, the directors do not expect a significant effect on the Group's consolidated financial statements resulting from<span class=\"_ _0\"></span> their adoption.7.2 <span class=\"_ _82\"> </span>Accounting standards and  <span class=\"_ _70\"> </span>interpretations published  <span class=\"_ _70\"> </span>by the IASB and not yet approved  <span class=\"_ _70\"> </span>by the European CommissionAt the date of this document, the competent bodies of the European Union have not yet completed the approval process necessary for the adoption of the amendments described below.\u2022 <span class=\"_ _6\"> </span>On 22 September 2022, the IASB published an amendment called \"<span class=\"ff63\">Amendments to IFRS 16 Leases: </span>Lease Liability in a Sale and Leaseback<span class=\"ff6f\">\". The document </span>aims to clarify how subsequent valuations by an entity in the context of a sale and leaseback transaction should take place. The amendments shall enter into force as of 1 January 2024, subject to any subsequent postponements determined in the course of approval by the European Commission, earlier application is however permitted.\u2022 <span class=\"_ _6\"> </span>On 23 January 2020, the IASB published \"<span class=\"ff63\">Amendments </span>to IAS 1 Presentation of Financial Statements: Classification of Liabilities as Current or Non-current<span class=\"ff6f\">\" </span>and on 31 October 2022 published an amendment entitled \"<span class=\"ff63\">Amendments to IAS 1 Presentation of </span>Financial Statements: Non-Current Liabilities with Cov<span class=\"_ _0\"></span>enants<span class=\"ff6f\">\".

The amendments shall enter into force as of 1 January 2024, subject to any subsequent postponements determined in the course of approval by the European Commission, earlier application is however permitted. The Group is currently evaluating the possible effects deriving from the introduction of the amendments indicated.8  <span class=\"_ _13\"> </span>PROPERTY<span class=\"_ _1\"></span>,<span class=\"_

The change in the scope of consolidation (548 million euros) refers mainly to the assets recognised in connection with the acquisition: (i) 100% of the share capital of Golar LNG NB 13 Corporation, owner of the FSRU vessel Golar Tundra (327 million euros, net of ancillary acquisition costs); (ii) of 6 and 19 companies engaged in the realisation<span class=\"_ _0\"></span> and management of plants for the promotion of circular economy projects for the energy valorisation of the organic fraction of waste - OFMSW and agricultural waste (158 million euros overall); (iii) of the control of Iniziative Biometano S.p.<span class=\"_ _4\"></span>A. (8 companies consolidated on a line-by-line basis) instead of joint control (37 million euros in total).During the year<span class=\"_ _0\"></span>, Snam capitalised 25 million euros of financial expenses (20 million euros in 2021). Depreciation (747 million euros), included rights-of<span class=\"_ _0\"></span>-use on leased assets, refers to economic and technical depreciation determined on the basis of the useful life of the assets or their remaining possible use by the Company, and, with<span class=\"_ _0\"></span> reference to leased assets, on the basis of the contractual duration if the exercise of any purchase options is not probable. Disposals (30 million euros, net of the related accumulated depreciation and impairment losses) mainly relate to assets in the transportation segment. Write-downs and reversals (126 million euros) mainly relate to assets in the transportation segment (116 million euros<span class=\"_ _0\"></span>) and mainly concern assets not yet available for use and sections of pipelines that are no longer usable.The value of plant and equipment includes the estimated (discounted) costs to be incurred for the removal of facilities and the restoration of sites (498 million euros, net of the provision for amortisation/depreciation) mainly relating to the natural gas storage (411 million euros) and transportation (68 million euros<span class=\"_ _0\"></span>) segments.Other changes (288 million euros) mainly concern: (i) the upward revision of the estimated costs for decommissioning and restoration of sites, basically relating to the storage sector<span class=\"_ _0\"></span>, against the reduction in the expected discount rates (228 million euros in all); (ii) contributions on works for interference with third parties (so-called \"recharges\", 25 million euros).Contractual commitments to purchase property, plant and equipment, and to provide services related to the construction thereof<span class=\"_ _0\"></span>, are reported in Note 26 \u201cGuarantees and commitments\u201d.

The markets in which these phenomena took place (including the Euro<span class=\"_ _0\"></span>zone), show a snapshot of 2022 characterised by 12the presence of widespread signs suggesting the existence of impairment indicators of an exogenous nature. Therefore, as at 31 December 2022, the test was performed for all major CGUs and CGU groupings, in particular: \u2022 <span class=\"_ _29\"> </span>for the sustainable mobility business, consisting of refuelling stations, and micro-liquefaction and bunk<span class=\"_ _0\"></span>ering plants, for 13the Snam4Mobility CGU, with reference to which, as at 31 December 2022, no goodwill remains allocated as a result of the impairment losses carried out; \u2022 <span class=\"_ _29\"> </span>for the A<span class=\"_ _0\"></span>GRI CGU (formerly the IES Biogas CGU) and the WASTE CGU (formerly the Renerwaste CGU), to which goodwill of 21 million euro and 29 million euros, respectively, is allocated. The companies respectively owned by IES Biogas group 14and the Renerwaste group each represent a single CGU (CGU AGRI and C<span class=\"_ _0\"></span>GU WASTE) as the method of managing raw material treatment plants (OFMSW in the case of WASTE plants and, agricultural biomass in the case of AGRI plants<span class=\"_ _0\"></span>) is unitary and centralised. Moreover, in view of the characteristics of such plants, management is not bound by the corporate structure when making decisions on the allocation of resources and investments; \u2022 <span class=\"_ _29\"> </span>for the energy efficiency business, by the grouping of Energy Efficiency CGUs, made up of the TEP Energy Solutions, 15Mieci, Evolve CGUs as well as by the Renovit sub-holding, to which a total goodwill of 19 million euros is allocated; this due to the strong vertical integration between the companies in the management of know-how and technologies, which allows the creation of important synergies in the presentation of a unitary offer to the market. The test was also performed for the Snam Rete Gas, ITG, GNL and Stogit CGUs belonging to the regulated activities of natural gas transportation, regasification and storage; limited to ITG, goodwill of 27 million euros is allocated.16Consistently (i) with the provisions of the agreement signed on 22 December 2022 between Snam Bioenerys group company and Femogas S.p.<span class=\"_ _4\"></span>A. and (ii) in light of the new strategic direction assigned to IES Biogas, which assumes the role of sub-holding company of the Snam group for the AGRI business, increasingly focusing its resources towards the management of proprietary plants aimed at the production of biogas/biomethane from biomass sources of agricultural 17origin, starting from 2022 the AGRI CGU includes, in addition to IES Biogas itself<span class=\"_ _3\"></span>, 24 additional companies. Specifically, these are the 20 companies that were acquired or established by IES Biogas during the year<span class=\"_ _0\"></span>, in addition to a further four companies that were already indirectly controlled by Snam as at 31 December 2022 and will become investee companies of IES Biogas by 2023.Overall, except for the amendments mentioned above, the impairment test was carried out on the basis of a similar CGU set<span class=\"_ _0\"></span>-up to last year<span class=\"_ _0\"></span>.The recoverable amount of the Snam4Mobility CGU was determined, as value in use, based on the cash flows of the corporate plans using the Discounted Cash Flow (DCF) Method. In consideration of the business development and in view of the proposed investment plan, the cash flows were calculated taking into consideration a longer time horizon compared with the forecast 2023-2026 Plan data, in order to be able to consider all the effects that may have a significant impact on these cash flows. The Weighted Average Cost of Capital - W<span class=\"_ _0\"></span>A<span class=\"_ _4\"></span>AC method was used to discount cash flows. The T<span class=\"_ _3\"></span>erminal Value was calculated using the<span class=\"_ _4\"></span> perpetuity method, applying a growth rate substantially in line with market evidence for the expected long-term inflation rate for the reference area, based on the values indicated by the International Monetary Fund ((IMF).With reference to the biogas/biomethane business, the recoverable value of the two CGUs identified, CGU AGRI and C<span class=\"_ _0\"></span>GU WASTE, was determined, as value in use, on the basis of the Discounted Cash Flow (DCF) Method, using the 2023-2026 Plan approved by the Board. For both CGUs, cash flows were calculated taking into consideration a longer time horizon compared to the forecast 2023-2026 Plan data approved by the Board, so as to consider all the effects that could have a significant impact on cash flows. The Weighted Average Cost of Capital - W<span class=\"_ _0\"></span>A<span class=\"_ _4\"></span>AC method was used to discount cash flows.  12 <span class=\"_ _d\"> </span>According to paragraph 12 of IAS 36.13 <span class=\"_ _d\"> </span>As a result of the updated strategic guidelines of the Mobility&amp;Liquefaction Business Unit, as reported in the half-year financial report as of June 30, 2022, in accordance with the provisions of IAS 36 \"Impairment Test,\" instead of the grouping of Mobility CGUs (consisting of Snam 4 Mobility CGU and Cubogas CGU), they were identified as two separate CGUs. As of December 31, 2022, the Cubogas CGU was not included in the scope of C<span class=\"_ _0\"></span>GUs because, as a result of impairments performed during the year<span class=\"_ _0\"></span>, the carrying value of fixed assets pertaining to the CGU was less than 1 million euro.14 <span class=\"_ _d\"> </span>The WASTE CGU in addition to the five companies present as of December 31, 2021, Renerwaste S.r.l., Renerwaste Lodi, Ecoprogetto Milano and Ecoprogetto T<span class=\"_ _0\"></span>ortona and Enersi, it also includes the six companies in the Waste business acquired during 2022: Cupello Renerwaste S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Anzio S.r.l, Biowaste CH4 Foligno S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Group S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Genova S.r.l., Biowaste CH4 T<span class=\"_ _0\"></span>uscania S.r.l.15 <span class=\"_ _d\"> </span>The difference compared to the 17 million euro present as of December 31, 2021 is due to the goodwill arising from the Esigen business, which was acquired by Mieci during 2022.16 <span class=\"_ _d\"> </span>The agreement, provides that Snam by 2023 will lose control of Iniziative Biometano and certain companies controlled by it, and in the same time frame, provides that IES Biogas will gain direct control of certain companies, now already controlled by the Snam group but directly participated by the same Iniziative Biometano.17 <span class=\"_ _d\"> </span>The 20 companies acquired or incorporated by IES Biogas are 1) Societ\u00e0 Agricola Asola Energie Biogas S.r.l., 2) Societ\u00e0 Agricola T<span class=\"_ _0\"></span>essagli Agroenergie S.r<span class=\"_ _0\"></span>.l., 3) Societ\u00e0 Agricola Santo Stefano S.r.l. 4) Societ\u00e0 Agricola Agrimezzana Biogas S.r<span class=\"_ _0\"></span>.l., 5) Societ\u00e0 Agricola Agrimetano S.r<span class=\"_ _0\"></span>.l.  6) Societ\u00e0 Agricola Carignano Biogas S.r.l.; 7) Emiliana Agroenergia Societ\u00e0 Agricola S.r<span class=\"_ _0\"></span>.l.;  8) Piacentina Agroenergia Societ\u00e0 Agricola S.r<span class=\"_ _0\"></span>.l.; 9) Societ\u00e0 Agricola San Giuseppe Agroenergia S.r.l.; 10) Societ\u00e0 Agricola La V<span class=\"_ _0\"></span>alle Green Energy S.r.l., 11) Societ\u00e0 Agricola Sangiovanni S.r<span class=\"_ _0\"></span>.l.; 12) Societ\u00e0 Agricola G.B.E.

Cash flows were calculated taking into consideration a longer time horizon compared to the forecast 2023-2026 Plan data approved by the Board, so as to consider all the effects that could have a significant impact on cash flows. The Weighted Average Cost<span class=\"_ _0\"></span> of Capital - WAAC method was used to discount cash flows. The Terminal V<span class=\"_ _0\"></span>alue was calculated using the perpetuity method, applying a growth rate in line with market evidence for the expected long-term inflation rate, based on the values indicated by the IMF<span class=\"_ _3\"></span>.With reference to the T<span class=\"_ _0\"></span>ransportation (Snam Rete Gas), Regasification (LNG) and Storage (Stogit) C<span class=\"_ _0\"></span>GUs, the recoverable value was defined as corresponding to the estimate of the value of the Net Invested Capital recognised in these assets for tariff purposes (R<span class=\"_ _4\"></span>AB - Regulatory Asset Base) by the Regulatory Authority for Energy, Networks and the Environment (ARER<span class=\"_ _4\"></span>A), including fixed assets valued using the revalued historical cost method, net working capital<span class=\"_ _0\"></span> flat rate, net of adjustments, including severance indemnities, where applicable, the decommissioning fund and the contributions received. The R<span class=\"_ _4\"></span>AB is also the reference basis for the determination of the service tariffs and, therefore, of the cash flows generated by the activities. With reference to the ITG CGU<span class=\"_ _0\"></span>, the recoverable value of the CGU was calculated as the usage value, based on the Discounted Cash Flow (DCF) Method, using the 2023-2026 Plan approved by the Board. The T<span class=\"_ _0\"></span>erminal Value, consistent with the practice in the energy infrastructure sector<span class=\"_ _0\"></span>, was determined as the disposal value at the end of the plan<span class=\"_ _0\"></span>'s time horizon, assuming the recognition of a premium in line with the market evidence examined as at 31 December 2022. For CGUs where the value in use is determined using the Discounted Cash Flow method, the reference discount rate is the WACC (W<span class=\"_ _0\"></span>eighted Average Cost of Capital - WAC<span class=\"_ _0\"></span>C), corresponding to the weighted average cost of capital, determined, consistently with the reference doctrine and prevailing methodological practices, based on the following main assumptions:\u2022 <span class=\"_ _29\"> </span>Risk F<span class=\"_ _0\"></span>ree Rate: the 10-year sovereign bond, issued by the country of reference, in which the CGU (or group of CGUs) operates is used to determine the risk-free rate;\u2022 <span class=\"_ _29\"> </span>Equity Risk Premium: the equity risk premium is determined by Snam on the basis of the main and authoritative external sources in the sector;\u2022 <span class=\"_ _29\"> </span>Beta Unlevered: calculated as the average figure recorded by the panel of comparable companies identified and specifically selected for each CGU; \u2022 <span class=\"_ _29\"> </span>D<span class=\"_ _3\"></span>/E: the debt-to-equity ratio is determined as an average parameter measured by the panel of comparable companies referring to each CGU;\u2022 <span class=\"_ _29\"> </span>Beta Relevered: it is calculated starting from the Beta Unlevered using the Hamada formula, which tak<span class=\"_ _0\"></span>es into account the tax effect, and the average D/E of the panel of comparable companies considered; \u2022 <span class=\"_ _29\"> </span>Reference Rate for the cost of debt: calculated as the average of the Swap Rate of ten-year instruments denominated in Euro;\u2022 <span class=\"_ _29\"> </span>Credit Spread: determined as an average parameter measured by the panel of comparable companies specifically selected for each CGU. The application of additional risks (Specific Risk Premium) is also envisaged aimed at reflecting, where applicable, within each discount rate, specific considerations referring to the aspects characterising a CGU (or group of CGUs<span class=\"_ _0\"></span>) such as, for example, risks of business or risks associated with the stage of development of the activities performed.Snam's methodology requires these values to be updated annually and, as at 31 December 2022, the WA<span class=\"_ _0\"></span>CCs estimated by the Snam Group and used in the impairment tests were between 5.57% and 8.97%.For all CGUs and CGU groupings, the recoverable value as represented above, was higher than their net book value, including the relevant goodwill, with the exception of the CGU Snam4Mobility<span class=\"_ _0\"></span>. In particular<span class=\"_ _0\"></span>, as at 31 December 2022, the filling station business was affected by: (i) the dynamics of gas prices, which negatively impacted the forecasts for the use of CNG as automotive fuel; (ii) the significant increase recorded in the main parameters (in particular<span class=\"_ _0\"></span>, the risk free rate and the reference rate used to determine the cost of debt) underlying the estimate of the weighted average cost of capital.A comparison between the recoverable amount and the carrying amount of the CGU Snam4Moblity showed a difference in value of 12 million euros, which led to the full write-down of goodwill, amounting to about 7 million euros, as well as of part of the tangible and intangible assets for the remaining amount of about 5 million euros.As required by accounting standard IA<span class=\"_ _4\"></span>S 36, the CGUs subject to impairment testing, whose recoverable value was determined by discounting the expected cash flows deriving from the use of the asset (as well as from its sale at the end of the useful life in some cases), were subjected to a sensitivity analysis of the recoverable amount, in the worst case scenario, which envisages a 0.5 percentage point increase in the discount rate applied during the impairment test. This stress test did not show significantly different results and led, in only one case limited to the WASTE CGU, to an impairment loss of about 5 million euros. 10EQUITY<span class=\"_ _0\"></span> INVESTMENTS<span class=\"_ _0\"></span> <span class=\"_ _0\"></span>ACCOUNTED<span class=\"_ _0\"></span> FOR USING<span class=\"_ _0\"></span> THE<span class=\"_ _0\"></span> EQUITY<span class=\"_ _0\"></span> METHOD(million euros<span class=\"_ _0\"></span>)<span class=\"_ _302\"> </span>31.12.2021<span class=\"_ _28e\"> </span>31.12.2022T<span class=\"_ _0\"></span>er\u00e9ga Holding S.A<span class=\"_ _4\"></span>.S. <span class=\"_ _316\"> </span>361<span class=\"_ _161\"> </span>398T<span class=\"_ _0\"></span>rans Austria Gasleitung GmbH (T<span class=\"_ _3\"></span>AG)<span class=\"_ _171\"> </span>556<span class=\"_ _161\"> </span>274AS Gasinfrastruktur Beteiligung GmbH<span class=\"_ _17f\"> </span>122<span class=\"_ _101\"> </span>93OL<span class=\"_ _32\"></span>T - Offshore LNG T<span class=\"_ _0\"></span>oscana S.p.A<span class=\"_ _4\"></span>.<span class=\"_ _1bb\"> </span>11<span class=\"_ _e6\"> </span>32Iniziative Biometano S.p.A<span class=\"_ _4\"></span>.

using the equity method.Disposals and redemptions (86 million euros) refer essentially to the sale of shares of Industrie De Nora S.p.A<span class=\"_ _4\"></span>. for the purpose of listing the company on the stock exchange, a transaction after which Snam holds 25.79% of the share capital (35.63% prior to the IPO), also taking into account capital increases of the same company that were not subscribed.Dividends received (107 million euros) mainly concern the associated companies Italgas (32 million euros<span class=\"_ _0\"></span>), Interconnector Limited (23 million euros), Galaxy (19 million euros<span class=\"_ _0\"></span>) and Senfluga (11 million euros) and the jointly controlled company T<span class=\"_ _0\"></span>er\u00e9ga (15 million euros<span class=\"_ _0\"></span>).The effect of the equity-accounting method recognised in income statement (144 million euros) refers to the share of the net results of companies valued using the equity method, mainly referring to jointly controlled and associated companies (positive results for totally 296 million euros and negative results for totally 152 million euros, of which 148 million euros related to associated company Galaxy Pipeline Assets HoldCo Limited.The effect of the equity-accounting method recognised in the statement of comprehensive income (130 million euros) is mainly attributable to the change in the fair value of hedging derivative financial instruments of the associate T<span class=\"_ _0\"></span>AP and<span class=\"_ _0\"></span> to exchange rate differences (euros/dollars) of the associate Galaxy Pipeline Assets HoldCo Limited.The macroeconomic context has been marked over the past 12 months by the presence of a significant inflationary phenomenon to which the major central banks, including the ECB, have responded with significant and repeated increases in their respective key interest rates. Therefore, as at 31 December 2022, Snam subjected all the main CGUs<span class=\"_ _0\"></span> represented by the equity investments held in jointly controlled companies and associated companies to impairment tests, verifying their recoverability by comparing their book value and their recoverable value, represented by the higher of fair value and value in use. In particular<span class=\"_ _0\"></span>, for carrying out the impairment test, the recoverable value of the equity investments was determined in the configuration of value in use on the basis of the Dividend Discount Model (DDM) or Discounted Cash Flow (DCF) methodology, with the exception of equity in Italgas S.p.A<span class=\"_ _4\"></span>. and Industrie De Nora S.p.<span class=\"_ _4\"></span>A., associated companies, for which the recoverable value was determined on the basis of market quotations at the closing date of the financial year<span class=\"_ _0\"></span>.As of 31 December 2022, the discount rates estimated by the Snam group and used in preparing the impairment tests ranged between 5.75% and 8.24% for CGUs measured using the DDM, and between 4.97% and 8.44% for CGUs<span class=\"_ _0\"></span> measured using the DCF<span class=\"_ _3\"></span>. With reference to the stake held by Snam S.p.A<span class=\"_ _4\"></span>. (84.47%) in T<span class=\"_ _0\"></span>AG, the company owning the pipeline that transports Russian gas to Italy through Austria, passing through Ukraine, Slovakia and up to the T<span class=\"_ _0\"></span>arvisio entr<span class=\"_ _4\"></span>y point, the continuation of the Russia-Ukraine conflict, which began in Februar<span class=\"_ _4\"></span>y 2022, led to a significant reduction in gas flows from Russia in the year recorded at the Baumgarten entry point<span class=\"_ _4\"></span>, equal to about 52.6% compared to 2021, with a consequent reduction in the volumes imported from the T<span class=\"_ _0\"></span>arvisio entr<span class=\"_ _4\"></span>y point (from about 29 billion standard cubic metres in 2021 to about 14 billion standard cubic metres in 2022). In addition, around 85% of the long-term transport capacity contracts expired on 31 December 2022. In a scenario characterised by significant uncertainties about duration and outcome of the conflict, with actions already taken by some states that will lead to the gradual independence of Europe from Russian gas, Snam determined the<span class=\"_ _0\"></span> estimated recoverable amount of the investment based on a multi-scenario approach, attributing a probability of occurrence to each of the scenarios considered. By multiplying the value in use emerging from each of the scenarios considered by the probability of occurrence attributed to them, the recoverable value was thus determined, resulting in a write-down of the equity investment held in T<span class=\"_ _0\"></span>AG of 340 million euros, with a value as at 31.12.2022 of 274 million euros.At the same time, the company is actively cooperating with the competent Austrian authorities on the definition of the regulatory framework applicable from 2025 (regulator<span class=\"_ _4\"></span>y period 2025-2028) in light of the changed context in which the company operates.   With reference to the stake held by Snam S.p.A<span class=\"_ _4\"></span>. (40%) in AS Gasinfrastruktur Beteiligung GmbH, the rise in interest rates, which adversely affected the recoverable value, resulted in a write-down of the investment by 25 million euros, with a value as at 31 December 2022 of 93 million euros.

In particular<span class=\"_ _3\"></span>, purchases were made in implementation of the following Authority Resolutions: (i) Resolution 165/2022/R/Gas, which provided for the procurement by Snam Rete Gas of volumes to cover system gas (about 0.6 billion cubic metres for a total countervalue of 706 million euros as at 31 December 2022); (ii) Resolution 274/2022/R/Gas, which defined the provisions for the filling 22service of last resort (about 1.4 billion cubic metres for a total counter<span class=\"_ _4\"></span>value of 2,348 million euros).The value of the inventories of gas purchased against these resolutions is offset by the recognition, for the same amount, of balance sheet liabilities.The provision for impairment losses essentially relates to the write-down (30 million euros), made in 2014, of 0.4 billion cubic metres of natural gas used in storage activities against strategic gas unduly withdrawn by some service users during 232010 and 2011.Non-current inventories include minimum quantities of natural gas that the storage companies are obliged to hold pursuant to Presidential Decree no. 22 of 31 January 2001 (so-called Compulsor<span class=\"_ _4\"></span>y inventories). The quantities of gas in storage, corresponding to approximately 4.5 billion standard cubic metres of natural gas, are 24determined annually by the Ministry of Economic Development.Inventories are not pledged to guarantee.

Amounts due to other lenders amounting to 202 million euros (2 million euros as of 31 December 2021) essentially refer to a T<span class=\"_ _0\"></span>erm Loan with a nominal value of 200 million euros to the parent company Cassa Depositi e Prestiti.There were no breaches of loan agreements as at the reporting date.Snam also has unused committed credit lines totalling 5.9 billion.<span class=\"ls0\"> </span>Financial covenants and negative pledge commitmentsAt 31 December 2022, Snam has bilateral and syndicated loan agreements in place with banks and other lenders that are not secured by collateral.Some of these agreements include, inter alia, compliance with typical international practice commitments, some of which are subject to specific materiality thresholds, such as, for example: (i) negative pledge commitments pursuant to which Snam and its subsidiaries are subject to limitations concerning the pledging of real property rights or other restrictions on all or part of the respective assets, shares or merchandise; (ii) pari passu and change-of-control clauses;<span class=\"_ _0\"></span> (iii) limitations on certain extraordinary transactions that the Company and its subsidiaries may carr<span class=\"_ _4\"></span>y out; and (iv) limits on the debt of subsidiaries.F<span class=\"_ _0\"></span>ailure to comply with these covenants, and the occurrence of other events such as cross- default events could result in Snam\u2019s failure to comply and, possibly, trigger the early repayment of the related loan. Exclusively for the EIB loans,<span class=\"_ _0\"></span> the lender has the option to request additional guarantees if Snam\u2019s credit rating is lower than BBB (Standard &amp; P<span class=\"_ _0\"></span>oor\u2019s/Fitch Ratings Limited) or Baa2 (Moody\u2019s) for at least two of the three ratings agencies.The occurrence of one or more of the aforementioned scenarios could have negative effects on Snam Group\u2019s operations, results, balance sheet and cash flow, resulting in additional costs and/or liquidity issues.At 31 December 2022, the financial debt subject to these restrictive clauses amounted to approximately 3 billion.Bonds issued by Snam as at 31 December 2022, with a nominal value of approximately 9.5 billion, referred to securities issued under the Euro Medium T<span class=\"_ _0\"></span>erm Notes programme. The covenants established for the programme<span class=\"_ _0\"></span>\u2019s securities are typical of international market practice and consist of<span class=\"_ _3\"></span>, inter alia, negative pledge and pari passu clauses. Specifically, under the negative pledge clause, Snam and its material subsidiaries are subject to limitations to pledging or maintaining encumbrances on all or part of their assets or proceeds to guarantee present or future debt, unless this is explicitly permitted.27 <span class=\"_ _d\"> </span>It excludes the depreciation of the upfront fees.  18.3 <span class=\"_ _34\"> </span>Breakdown of net financial debtThe following table provides a breakdown of net financial debt, showing transactions with related parties:(million euros<span class=\"_ _0\"></span>)<span class=\"_ _302\"> </span>31.12.2021<span class=\"_ _28e\"> </span>31.12.2022A. + B.

CHARGESThe provision for decommissioning and site restoration (Euro 498 million) includes the discounted estimate of costs expected to be incurred for the removal of facilities and the restoration of sites essentially in the natural gas storage (411 28million euros) and transportation (68 million euros) segments. The discounting for the provision for decommissioning and site restoration was carried out using the corresponding to the euro area Corporate Bond returns with an \u201c<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>A<span class=\"_ _0\"></span>\u201d rating. The rate thus determined is approximately 3.7%. The last deadline in chronological order for disbursements related to the dismantling and restoration storage sites refers to the Bordolano concession, in 2041. The change in the scope of consolidation (8 million euros) refers to the acquisition of the companies operating in the biomethane business.The other changes (228 million euros) mainly refer to the effects deriving from the increase in the discount rates, mainly referring to the natural gas storage and transportation segment and partially off-set by inflation rates.  Other provisions for risks and charges (44 million euros) mainly concern: (i) charges that the Group<span class=\"_ _0\"></span>\u2019s insurance company Gasrule Insurance DAC expects to incur for insured claims (22 million euros<span class=\"_ _0\"></span>); (ii) the provision for voluntary redundancies (7<span class=\"_ _4\"></span> million euros); (iii) the provision relating to the estimate of probable charges of a fiscal and financial nature (7 million euros<span class=\"_ _0\"></span>). 28 <span class=\"_ _d\"> </span>The costs refer to the estimated expenses for the removal of the connection works to the Livorno LNG regasification terminal - OL<span class=\"_ _32\"></span>T Offshore LNG T<span class=\"_ _0\"></span>oscana. 29The sensitivity of the discount rate represents the

_4\"></span>TS<span class=\"_ _a9\"> </span>36<span class=\"_ _101\"> </span>27Liabilities for employee benefits, in the amount of 27 million euros, decreased by 9 million euros, mainly due to the increase in expected discount and inflation rates.The provision for employee severance pay (TFR), governed by Article 2120 of the Italian Civil Code, represents the estimated liability determined on the basis of actuarial procedures for the amount to be paid to employees at the time that the employment is terminated. The principal amount of the benefit is equal to the sum of portions of the allocation calculated on compensation items paid during the employment and revalued until the time that such relationship is terminated. Due to the legislative changes introduced from 1 January 2007 for companies with more than 50 employees, a significant part of severance pay to be accrued is classified as a defined-contribution plan since the company\u2019s only obligation is to pay the contributions to the pension funds or to INPS. Liabilities related to severance pay pre-dating 1 January 2007 remain a defined-benefit plan to be valued using actuarial methods. 30FISDE includes the estimated actuarially determined charges for the contributions to be paid to serving and retired managers. 30 <span class=\"_ _d\"> </span>For executives in service, contributions are calculated from the year in which the employee retires and refer to the years of service provided. 31FISDE provides financial supplementary healthcare benefits to Eni Group executives and retired executives whose most recent contract of employment was as an executive with the Eni Group. FISDE is funded through the payment of: (i) contributions by member companies; (ii) contributions paid by Shareholders for themselves and their immediate family; and (iii) ad hoc contributions for specific benefits. The amount of the liability and the healthcare cost are determined on the basis, as an approximation of the estimated healthcare expenses paid by the fund, of the contributions paid by the company in favour of pensioners.The early retirement fund refers to expenses incumbent upon the employer from application of the implementation agreement, relating to the early retirement instrument for employees regulated pursuant to Article 4 paragraphs 1 - 7 of Law 92/2012 (the \u201cFornero Law\u201d).Deferred monetary incentive plans are allocated to executives who have met the goals set out in the year preceding the allocation year<span class=\"_ _0\"></span>, and allocate a basic incentive that is disbursed after three years and varies according to the performance achieved by the Company during the course of the three-year period following the time of the allocation. The benefit is provisioned when Snam\u2019s commitment to the employee arises. The estimate is subject to revision in future periods, based on the final accounting and updates to profit forecasts (above or below target).  The long-term monetary incentive plans, involve the granting and payment<span class=\"_ _4\"></span>, of a variable monetary bonus tied to a measure of company performance. Obtaining the benefit depends on the achievement of certain future performance levels and is conditional on the beneficiary remaining with the Company for the three-year period following the allocation (the \u201cvesting period\u201d). This benefit is allocated pro rata over the three-year period depending on the final performance parameters. From 2017, the new share-based variable long-term incentive plan (equity IL<span class=\"_ _1\"></span>T<span class=\"_ _4\"></span>) was introduced instead of the 32long-term monetary incentive plans (IMD and IL<span class=\"_ _32\"></span>T<span class=\"_ _4\"></span>).Seniority bonuses are benefits paid upon reaching a minimum service period at the company and are paid in kind in the form of goods and/or services.The composition and changes in liabilities for employee benefits, determined by applying actuarial methods, are as follows: 31.12.2021<span class=\"_ _32e\"> </span>31.12.2022(million euros<span class=\"_ _0\"></span>)Iso-Other Other TFR<span class=\"_ _48\"> </span>FISDEpension T<span class=\"_ _3\"></span>otal<span class=\"_ _194\"> </span>TFR<span class=\"_ _9\"> </span>FISDET<span class=\"_ _3\"></span>otalliabilitiesliabilitiesFundOPENING LIABILITIES FOR EMPL<span class=\"_ _0\"></span>O<span class=\"_ _0\"></span>YEE 25<span class=\"_ _bd\"> </span>6<span class=\"_ _cb\"> </span>6<span class=\"_ _4d\"> </span>3<span class=\"_ _77\"> </span>40<span class=\"_ _84\"> </span>26<span class=\"_ _bd\"> </span>7<span class=\"_ _4d\"> </span>3<span class=\"_ _77\"> </span>36BENEFITSCosts related t<span class=\"_ _0\"></span>o current services (recognized 1<span class=\"_ _192\"> </span> (4)<span class=\"_ _1b9\"> </span><span class=\"ff63\"> (3)<span class=\"_ _d8\"> </span></span>1<span class=\"_ _1b3\"> </span><span class=\"ff63\">1</span>in \"personnel costs\")Actuarial (gains)/losses resulting from experience adjustments (recognised in other 1<span class=\"_ _2ee\"> </span><span class=\"ff63\">1</span>components in the comprehensiv<span class=\"_ _0\"></span>e income statement)Actuarial (gains) / losses resulting from changes in financial assumptions (recognised 1<span class=\"_ _bd\"> </span>1<span class=\"_ _34e\"> </span><span class=\"ff63\">2<span class=\"_ _207\"> </span></span> (5)<span class=\"_ _c7\"> </span> (3)<span class=\"_ _34f\"> </span><span class=\"ff63\"> (8)</span>in other components in the comprehensiv<span class=\"_ _0\"></span>e income statement)Benefits paid<span class=\"_ _197\"> </span> (2)<span class=\"_ _192\"> </span> (2)<span class=\"_ _34f\"> </span><span class=\"ff63\"> (4)<span class=\"_ _207\"> </span></span> (2)<span class=\"_ _2b3\"> </span><span class=\"ff63\"> (2)</span>CL<span class=\"_ _0\"></span>OSING LIABILITIES 26<span class=\"_ _bd\"> </span>7<span class=\"_ _247\"> </span>3<span class=\"_ _70\"> </span>36<span class=\"_ _298\"> </span>20<span class=\"_ _bd\"> </span>4<span class=\"_ _4d\"> </span>3<span class=\"_ _70\"> </span>27FOR EMPL<span class=\"_ _0\"></span>O<span class=\"_ _0\"></span>YEE BENEFITS31 <span class=\"_ _d\"> </span>The fund provides the same benefits for Snam Group executives.  32 <span class=\"_ _d\"> </span>For more information on the characteristics of this plan, refer to the \u201cOther information\u201d paragraph of the Directors\u2019 Report.

At present, it has been decided not to adopt specific hedging policies for these exposures. For instance, it should be noted that the effects of exchange rate differences deriving from the difference in translation into currency presentation (euro) of the functional currencies of these companies are recognised in the Comprehensive Income Statement.   Snam policies and principles for the management and control of financial risks are described below, in accordance with<span class=\"_ _0\"></span> the approach set out in IFRS 7 - Financial Instruments: Disclosures.27.2 <span class=\"_ _34\"> </span>Risk of changes in interest rates The risk of changes in interest rates is associated with fluctuations in interest rates affecting the market value of the Company\u2019s financial assets and liabilities and its net financial expense. Snam\u2019s objective is to optimize the interest rate risk while pursuing its financial objectives. Snam Group has adopted a centralised organisational model. In accordance with this model, Snam\u2019s various departments access the financial markets and use funds to cover financial requirements, in compliance with approved objectives, ensuring that the risk profile stays within defined limits. At 31 December 2022, the Snam Group used external financial resources in the form of bond loans and bilateral and syndicated loans with banks and other financial institutions, in the form of medium- to long-term loans and bank credit lines at interest rates indexed to the reference market rates, in particular the E<span class=\"_ _0\"></span>urope Interbank Offered Rate (Euribor), and at fixed rates. The exposure to the risk of changes in interest rates at 31 December 2022, taking into account the hedging transactions put in place, was approximately 20% of the total exposure of the Group (28% at 31 December 2021). At 31 December 2022, Snam had interest rate swap (IRS) derivative contracts in place for a notional total of 106 million euros, relating to hedges on a 106 million euros floating-rate bond maturing in 2024. Though the Snam Group has an active risk management policy, the rise in interest rates relating to floating-rate debt not hedged against interest rate risk could have negative effects on Snam Group\u2019s operations, equity situation and financial position. E<span class=\"_ _0\"></span>ven considering the limited exposure to changes in interest rates, limited to 20% of the Group\u2019s total exposure and fully attributable to the Euribor rate, a possible change in the method of calculating the latter and the related fall-back clauses that may be formulated could result in the Snam Group having to adjust the financial contracts that may be affected by the aforementioned change and/or the management of prospective cash flows.The effects on shareholders\u2019 equity and net profit at 31 December 2022 are shown below, assuming a h<span class=\"_ _0\"></span>ypothetical change in the interest rate basis points of +/-10% actually applied during the course of the year:31.12.2022Other components Income st<span class=\"_ _0\"></span>atement in the compr<span class=\"_ _0\"></span>ehensive (million euros<span class=\"_ _0\"></span>)resultincome st<span class=\"_ _0\"></span>atementInterest  Interest   Interest  Interest   +10 bps-10 bps+10 bps-10 bpsInterest rate change effect<span class=\"_ _1e0\"> </span><span class=\"ls0\"> (3)<span class=\"_ _52\"> </span>3<span class=\"_ _b0\"> </span> <span class=\"_ _167\"> </span> </span>Impacts gross of tax effect<span class=\"_ _35d\"> </span> (3)<span class=\"_ _52\"> </span>3T<span class=\"_ _0\"></span>ax effect<span class=\"_ _178\"> </span>1<span class=\"_ _235\"> </span> (1)IMP<span class=\"_ _0\"></span>ACTS NET OF T<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>X EFFECT<span class=\"_ _16c\"> </span> (2)<span class=\"_ _52\"> </span>2(*)  The change in the interest rate impacts on the change of fair value of derivative hedging instruments rec<span class=\"_ _0\"></span>ognised amongst other components in the comprehensive inc<span class=\"_ _0\"></span>ome statement and, therefore, does not impact on the income statement result.27.3 <span class=\"_ _34\"> </span>Credit risk Credit risk is the Company\u2019s exposure to potential losses arising from counterparties failing to fulfil their obligations. Default on or delayed payment of fees may have a negative impact on Snam's economic results and financial balance. For the risk of non-compliance by the counterparty concerning contracts of a commercial nature, the credit management for credit recovery and any disputes are handled by the business units and the centralised Snam departments. For trade receivables, provisions for bad debts reflect the value of expected losses over the life of the receivable and are made on the basis of the expected credit loss model or specifically on credit positions that present special risk elements. For further details, please refer to Note 5 \"Significant Accounting Policies - Financial assets measured at amortized cost\".Snam, as far as regulated activities are concerned, which currently represent almost all activities, provides its business services to 230 operators in the gas sector, with 10 operators representing appro<span class=\"_ _0\"></span>ximately 67% of the entire market (Eni, Edison and Enel Global T<span class=\"_ _0\"></span>rading hold the top three spots). The rules for Costumer access to the services offered are established by the Authorities and set out in the Network Codes.For each type of service, these documents explain the rules regulating the rights and obligations of the parties involved in selling and providing said services and contain contractual conditions, which significantly reduce the risk of customer default. The Codes contain guarantees to be provided to cover the obligations undertaken. In certain cases, if the customer has a credit rating issued by leading international organisation, the issuing of these guarantees can be mitigated. The regulations also contain specific clauses which guarantee the neutrality of the entity in charge of balancing, an activity carried out from 1 December 2011 by Snam Rete Gas as the major transportation company. In particular<span class=\"_ _3\"></span>, the current balancing rules require that Snam, on the basis of financial merit criteria, mainly, operates in buying and selling on the GME balancing platform to guarantee the necessary resources for the safe and efficient movement of gas from the injection points to the withdrawal points in order to guarantee the constant equilibrium of the network.  As regards non-regulated activities, which will become increasingly important over the Plan time horizon, the Company, through its centralised functions, performs a prior analysis of the financial soundness of counterparties in order to minimise this risk.Snam\u2019s maximum exposure to credit risk as at 31 December 2022 is represented by the book value of the financial assets recorded in the financial statements, detailed in Note 15 \u201cTrade and other receivables\u201d.The following table shows a breakdown of trade and other receivables by maturity, indicating the gross value and the value net of the provision for impairment losses:31.12.2021<span class=\"_ _136\"> </span>31.12.2022(million euros<span class=\"_ _0\"></span>)T<span class=\"_ _3\"></span>rade Other T<span class=\"_ _3\"></span>rade Other (*)(*)rec<span class=\"_ _0\"></span>eivables rec<span class=\"_ _0\"></span>eivables T<span class=\"_ _3\"></span>otalT<span class=\"_ _3\"></span>otalrec<span class=\"_ _0\"></span>eivables rec<span class=\"_ _0\"></span>eivables Non-overdue receivables<span class=\"_ _159\"> </span>2,412<span class=\"_ _14d\"> </span>602<span class=\"_ _5e\"> </span>3,014<span class=\"_ _51\"> </span>3,686<span class=\"_ _160\"> </span>380<span class=\"_ _62\"> </span>4,066Overdue receivables:<span class=\"_ _6f\"> </span>317<span class=\"_ _185\"> </span>317<span class=\"_ _169\"> </span>558<span class=\"_ _185\"> </span>558   - from 0 to 3 months<span class=\"_ _10e\"> </span>116<span class=\"_ _185\"> </span><span class=\"ff6b\">116<span class=\"_ _169\"> </span></span>345<span class=\"_ _185\"> </span><span class=\"ff6b\">345</span>   - from 3 to 6 months<span class=\"_ _b4\"> </span>54<span class=\"_ _1e6\"> </span><span class=\"ff6b\">54<span class=\"_ _16d\"> </span></span>60<span class=\"_ _1e6\"> </span><span class=\"ff6b\">60</span>   - from 6 to 12 months<span class=\"_ _b4\"> </span>8<span class=\"_ _1f5\"> </span><span class=\"ff6b\">8<span class=\"_ _16d\"> </span></span>23<span class=\"_ _1e6\"> </span><span class=\"ff6b\">23</span>   - beyond 12 months<span class=\"_ _ce\"> </span>139<span class=\"_ _185\"> </span><span class=\"ff6b\">139<span class=\"_ _169\"> </span></span>130<span class=\"_ _185\"> </span><span class=\"ff6b\">130</span>T<span class=\"_ _0\"></span>otal trade receivables and other 2,729<span class=\"_ _160\"> </span>602<span class=\"_ _62\"> </span>3,331<span class=\"_ _51\"> </span>4,244<span class=\"_ _160\"> </span>380<span class=\"_ _62\"> </span>4,624receivables(*)   The values are shown net of provision for bad debt of an amount equal t<span class=\"_ _0\"></span>o 100 million euros (85 million at 31 December 2021).The net book value of trade receivables past due at 31 December 2022 and not written down, amounting to 558 million euros, mainly refers to trade receivables of companies operating in regulated businesses; in particular they refer to: (i) the transportation segment (442 million euros), mainly for receivables from users related to balancing and settlement service items. These receivables fall within the neutrality mechanisms envisaged by the current regulatory framework; (ii) to the storage segment (77 million euros), in particular V<span class=\"_ _3\"></span>A<span class=\"_ _0\"></span>T invoiced to users for the use of strategic gas unduly withdrawn and not replenished by them within the terms established by the Storage Code during 2010 and 2011. As provided for under the applicable legislation, notices of V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T changes may be issued at the end of bankruptcy proceedings and unsuccessful enforcement proceedings.The following is a description of the credit recovery activities carried out against certain users of the transportation and balancing system and the storage system.2<span class=\"_ _0\"></span>7<span class=\"_ _0\"></span>.<span class=\"_ _3\"></span>3.<span class=\"_ _3\"></span>1 <span class=\"_ _33\"> </span>Recovering receivables from certain users of the transportation and balancing system   The balancing service ensures that the network is safe and that costs are correctly allocated between the market operators. Balancing has both a physical and a commercial purpose. The physical balancing of the system consists of the<span class=\"_ _0\"></span> set of operations through which the Dispatching department of Snam Rete Gas controls flow parameters (capacity and pressure) in real time in order to ensure that gas can move safely and efficiently from injection points to withdrawal points at all times. Commercial balancing consists of the activities required to correctly schedule, account for and allocate the transported gas, as well as the fee system that encourages users to maintain a balance between the volumes they inject into and withdraw from the network. Pursuant to the balancing regime, which was introduced by Resolution ARG/gas 45/11 and came into effect on 1 December 2011, in its role as Balancing Supervisor, Snam Rete Gas must ensure that it procures the quantities of gas<span class=\"_ _0\"></span> required to balance the system and offered on the market by users through a dedicated platform of the Gestore dei Mercati Energetici (GME), and, accordingly<span class=\"_ _0\"></span>, it must financially settle the imbalances of individual users by buying and selling gas on the basis of a benchmark unit price (the \u201cprinciple of economic merit\u201d). The Company must also ensure that it recovers sums owed for the settlement of imbalances from any defaulting users. <span class=\"ls0\"> </span>Unpaid receivables relating to the period from 1 December 201<span class=\"_ _3\"></span>1 to 23 October 2012The initial regulation laid down by the Authority with Resolution ARG/gas 155/11 stated that Users had to provide specific guarantees to cover their exposure and, where Snam Rete Gas had performed its duties diligently and had not been able to recover the costs related to provision of the service, these costs would have been recovered through a special fee determined by the Authority.36With a subsequent resolution 351/2012/R/ gas, the Authority provided for the application of the CVBL variable unit fee to cover uncollected receivables, arranging for the charges to be recovered to be spread over a minimum of 36 months with a maximum monthly amount of 6 million euros.The Authority subsequently launched a fact<span class=\"_ _0\"></span>-finding investigation into the way in which the balancing service was provided for<span class=\"_ _4\"></span> 37the period between 1 December 2011 and 23 October 2012. The investigation was closed by Resolution 144/2013/E/gas of 5 April 2013. On the same date, the Authority: (i) opened proceedings to determine the share of costs arising from uncollected receivables owing to the gas balancing supervisor for the period 1 December 2011 - 23 October 2012; and (ii) opened six<span class=\"_ _4\"></span> proceedings aimed at establishing whether there have been violations regarding the natural gas balancing service.<span class=\"_ _4\"></span> With regard to the preliminary investigation discussed in point (i) above, the proceedings were closed by means of Resolution 608/2015/R/gas, with which the Authority decided not to pay a share of the uncollected receivables in relation to specific cases analysed in the preliminary investigation, in any case subject to Snam Rete Gas\u2019s right to withhold the receivables relating to the income statement entries on balancing, possibly already recuperated. The Company appealed Resolution 608/2015/R/gas, before the Regional Administrative Court of Milan, which partially admitted the appeal submitted by the Company with ruling 942/2017; this was in turn partially appealed by the Company and the Authority. The judgement was then confirmed by Council of State judgement no. 1630/2020.During the above-mentioned investigation period, Snam Rete Gas, having terminated the transportation contracts of the six users involved in the aforementioned proceedings since they either defaulted on payments or failed to comply with the balancing obligations set forth in the industry regulations and the Network Code, initiated steps to recover the receivables relating to balancing and transport items.The competent legal authorities have issued eleven provisionally enforceable injunction orders, six of which relate to receivables 38related to the balancing service and five to receivables for the transportation ser<span class=\"_ _4\"></span>vice, for which Snam Rete Gas has initiated enforcement procedures that have led to the recovery of negligible amounts with respect to the overall debt position of the<span class=\"_ _4\"></span> Users, also in consideration of the bankruptcy procedures initiated in the meantime by all the users in question.36 <span class=\"_ _d\"> </span>The aforementioned resolution was annulled pursuant to the ruling 1587/2014 of the Regional Administrative Court of Milan insofar as the obligation of Users to pay the CVBL consideration of 0.001 \u20ac/Scm with effect from 1 October 2012. Moreover, with the subsequent Resolution 372/2014/R/gas the coefficient was redefined at the same amount of 0.001 \u20ac/Scm.37 <span class=\"_ _d\"> </span>The time period set for the preliminary investigation which was initially limited to 1 December 2011 - 31 May 2012, was subsequently extended to 23 October 2012.38 <span class=\"_ _d\"> </span>The users in question have appealed against some of these injunctions. Specifically, as well as requesting the suspension of the provisional enforceability and the revocation and/or declaration as null and void of the injunctions themselves, three users have submitted counterclaims requesting that Snam Rete Gas be ordered to compensate them for alleged damage suffered. The oppositions were declared null and void, with the resulting lapse of the demand and the passage into judgement of the injunction decrees.In particular<span class=\"_ _0\"></span>, at present:\u2022 <span class=\"_ _29\"> </span>five Users were declared bankrupt. With regard to all five Users, Snam Rete Gas obtained measures for admission to the list of creditors for the receivable owed, plus interest. As part of these proceedings, a proposal for arrangement with creditors was submitted and approved by the majority of the creditors; the bankruptcy proceedings, following the final distribution, were closed. A second procedure was also closed after approval and execution of the final distribution; \u2022 <span class=\"_ _29\"> </span>a User applied for admission to the arrangement procedure and the Judicial Authority issued the approval 39of the arrangement.  Unpaid receivables after 23 October 2012In 2013, two further transportation contracts were terminated and Snam Rete Gas initiated injunction proceedings.It obtained three payment orders, of which two for receivables relating to the balancing service and one<span class=\"_ _4\"></span> for the transportation service. Both Users appealed, with<span class=\"_ _4\"></span> the relative rulings rejecting the claims and consolidating the securities acquired by Snam Rete Gas. The executive procedures that were initiated resulted in a negligible recovery of amounts when compared to the overall<span class=\"_ _4\"></span> amounts due from the Users which were then declared bankrupt. Snam Rete Gas regularly submitted its claims in the respective arrangements with creditors. The insolvency proceedings both ended with the recovery of minimal<span class=\"_ _4\"></span> amounts with respect to the bankrupt company's overall debt.In 2014, a further transport contract was terminated and Snam Rete Gas initiated provisional executive procedures for recovery of the receivables, one relating to balancing<span class=\"_ _4\"></span> services and the other to transportation ser<span class=\"_ _4\"></span>vices. The User was declared bankrupt and Snam Rete Gas was admitted to the current list of creditors for the entire debt due, plus interest. Finally, in 2015 a further transportation contract was terminated and Snam Rete Gas initiated debt recovery<span class=\"_ _4\"></span> measures, securing two provisional executive injunctions against the User<span class=\"_ _0\"></span>, one for the balancing service and the other for the transport service. The User was subsequently<span class=\"_ _4\"></span> declared bankrupt and Snam Rete Gas has regularly submitted its claims for the arrangements with creditors. Given the insolvency of the bankrupt, the bankruptc<span class=\"_ _4\"></span>y proceedings ended without recovery of any sums. Snam Rete Gas, as stated in the provisional executive injunctions issued by the Court, has engaged in proper conduct and complied with the provisions of the transportation contract, the Network Code and, more generally, the applicable legislation.39 <span class=\"_ _d\"> </span>In respect of the approval provision, a claim was brought before the Court of Appeal of Turin, and \u2013 in respect to the confirmation procedure adopted by the same Court \u2013 the appeal was brought before the Court of Cassation, which subsequently rejected the appeal.Lastly, we note that on 12 February 2016 the Public Prosecutor at the Court of Milan ordered the urgent preventive seizure of the moveable and fixed assets belonging to companies and attributable in various guises to the above-mentioned five Users. In May 2017, the investigation was concluded and the investigated parties were charged with the being involved in a criminal association and committing aggravated fraud against Snam Rete Gas. At the preliminary hearing set for 19 December<span class=\"_ _4\"></span> 2018, the Judge accepted Snam Rete Gas joining the proceedings as a civil party. The Court granted the pre-trial requests and declared the trial open. Following the conclusion of the preliminary hearing, the<span class=\"_ _4\"></span> Court on 15 February 2023 recognized the criminal liability of the defendants, condemning them, inter alia, to pay compensation for damages in favor of Snam Rete Gas. We are awaiting the filing of the reasons for the sentence, which is set within 90 days. These criminal proceedings resulted in the formal complaint report (and subsequent supplementary reports) filed by Snam Rete Gas, as offended party, in October 2012 for the crimes of falsehood and aggravated fraud. 27.3.2 <span class=\"_ _29\"> </span>Recovering receivables from users<span class=\"_ _4\"></span> <span class=\"_ _0\"></span><span class=\"ls0\"> </span>of the storage system<span class=\"_ _4\"></span> Withdrawals made from strategic storage by three users, invoiced by Stogit and not replenished by the user under the terms specified by the Storage CodeFollowing withdrawals from strategic storage made by a User in November and December 2010, Stogit asked for and obtained an injunction with regard to the sums due that the user failed to pay.<span class=\"_ _3\"></span>The provisional enforceability was confirmed during the opposition launched by the opposing party. The appropriate executive actions were launched as a result.Following the withdrawals and the failure to replenish the strategic gas in the initial months of 2011 as well, Stogit requested and obtained a second provisional executive injunction for the further sums accrued.Urgent proceedings were also launched for the replenishment of all the gas unlawfully withdrawn, concluding with the conviction of the debtor<span class=\"_ _0\"></span>, with the subsequent application for injunctive relief also being rejected. In 2012 the above user together with another two users (who also defaulted with regard to Stogit) were added to the proceedings for an arrangement with creditors, in which Stogit formally transmitted and documented the amounts of its receivables with these users.Moreover<span class=\"_ _0\"></span>, following the sub-proceedings to dismiss<span class=\"_ _0\"></span> the arrangement, the Court of Asti declared two of the above-mentioned users bankrupt. In both cases, Stogit promptly filed a proof of claim and its receivables were admitted in full.However<span class=\"_ _0\"></span>, the procedure for an arrangement with<span class=\"_ _0\"></span> creditors is continuing with regard to the third user<span class=\"_ _0\"></span>,<span class=\"_ _0\"></span> which was appealed by one of the creditors. The Court of Appeal of Turin issued a ruling, confirming the approval<span class=\"_ _0\"></span> of the arrangement with creditors.<span class=\"ls0\"> </span>Withdrawals made from strategic storage by a user<span class=\"_ _3\"></span>, invoiced by Stogit and not replenished by the User under the terms specified by the StorageCode, ascribable to the 2010-201<span class=\"_ _3\"></span>1 and 201<span class=\"_ _0\"></span>1-2012thermal yearsStogit filed with the Civil Court of Milan for a payment injunction provisionally enforceable against one User pursuant to Article 186- ter<span class=\"_ _0\"></span>.At present, following the partial restitution of gas in the wake of legal action brought, Stogit is still owed approximately 23.6 million euros SCM.  Stogit has therefore taken the appropriate actions.The Court of Rome then declared the User bankrupt and Stogit submitted its claim, which was accepted.<span class=\"ls0\"> </span>Withdrawals made from strategic storage by a User<span class=\"_ _3\"></span>, invoiced by Stogit and not replenished by the User under the terms specified by the Storage Code, relating to October and November 201<span class=\"_ _3\"></span>1Stogit filed with the Civil Court of Milan for a provisionally enforceable payment injunction, brought because of improper withdrawals, in respect of which Stogit still was owed approximately 56.0 million euros SCM.While the proceedings were ongoing, the Court of Rome declared the User bankrupt. Consequently, the Civil Court of Milan declared the case interrupted and Stogit submitted its claim, which was accepted, during which the final distribution of assets was made and, consequently, in 2020, the proceedings were closed, during which no amounts were paid to the Company.27.4 <span class=\"_ _34\"> </span>Liquidity risk Liquidity risk is the risk that new financial resources may<span class=\"_ _0\"></span> not be available (funding liquidity risk) or that the Company may be unable to convert assets into cash on the market (asset liquidity risk), meaning that it cannot meet its payment commitments.<span class=\"_ _3\"></span>This may affect profit or loss should the Company be obliged to incur extra costs to meet its commitments or<span class=\"_ _0\"></span>, in extreme cases, lead to insolvency and threaten the Company\u2019s future as a going concern.Under the financial plan, Snam\u2019s risk management system aims to establish a financial structure that, in line with the business objectives, ensures sufficient liquidity for the Group, minimising the relative opportunity cost and maintaining a balance in terms of the duration and composition of the debt.The financial market is characterised by a continuous growth of sources of financing for companies able to improve the environmental impact of their investments. The interest of the investors is linked and subordinated to the ability of the companies themselves to achieve certain objectives in terms of environmental sustainability.  With a view to the correct management of liquidity risk, the diversification of funding sources also through the use of sustainable finance instruments is therefore crucial to guarantee companies wide access to financial markets at competitive costs, with consequent positive effects on the economic situation, equity and financial position of the companies themselves. Similarly, for Snam, the failure to achieve certain KPIs in the ESG area, within the general objective of the Group to make its business more sustainable in the medium-long term, could lead to higher financing costs or to the lack of access to some sources of funding.Mitigation of this risk is based on Snam's extreme attention to ESG issues, traditionally a significant and structured part of the company's strategy.<span class=\"_ _0\"></span> Consistent with this approach, during 2018 Snam finalised the transformation of its 3.2 billion euros syndicated credit lines into sustainable loans, constituting at the time the third largest sustainable loan signed in the world and the first by a gas utility. This loan provides for bonus/ malus mechanisms based on the achievement of certain KPIs in the ESG (Environment, Social, Governance) area. In addition, Snam issued (i) in February 2019, its first 500 million euros Climate Action Bond, (ii) between 2020 and 2021 T<span class=\"_ _0\"></span>ransition Bonds for 2,350 million euros (iii) in January 2022, the inaugural dual-tranches Sustainability-linked Bond (SLB<span class=\"_ _0\"></span>) for 1.5 billion euros, whose economic performance is linked to the achievement of certain sustainability targets, and (iv) in November 2022 the inaugural EU T<span class=\"_ _0\"></span>axonomy-Aligned T<span class=\"_ _0\"></span>ransition Bond for 300 million euros. These are aimed at financing investments in environmental sustainability and energy transition, while for SLB instruments the return is linked to the achievement of methane and CO emission reduction targets. It should 2be noted that the January 2022 issue was associated with a Liability Management exercise that led to the repurchase of 350 million euros of bonds to proactively manage future debt maturities and accelerate the transition from plain vanilla bonds to sustainable finance instruments. In 2022, Snam finalised with major relationship banks (i) Revolving Credit F<span class=\"_ _0\"></span>acilities (RCF) for a total of 1.2 billion euros, of which 1.1 billion euros in KPI-linked format (ii) bank loans for 375 million euros, of which 275 million euros in Green loan and KPI-linked format and (iii) a bank loan agreement for 1.5 billion euros with a maximum term of 24 months. During 2020, Snam also renewed its Euro Commercial Paper programme, increased from 2 to 2.5 billion euros, linking it to environmental and social sustainability objectives in line with the sustainable loan and obtaining an ESG rating for the instrument equal to EE assigned by the ESG rating company Standard Ethics, confirmed in 2021 and increased to EE+ in 2022. Finally, in June 2021, Snam signed a loan agreement with the European Investment Bank (EIB) for a total of 150 million euros to support the group's energy efficiency projects in the residential and industrial sectors. Specifically, the agreement concerns initiatives totalling 200 million euros planned by the subsidiary TEP Energy Solutions, which consist mainly in the energy upgrading of residential buildings and the implementation of energy efficiency and decarbonisation measures for industrial activities, including the installation of photovoltaic panels. The loan is characterised by a framework loan structure, which can be used in several tranches within a period of three years; each tranche will have a maximum total duration of 15 years. As at 31 December 2022, this line was utilised for approximately 110 million euros. As shown in section 27.2 \u201cRisk of changes in interest rates\u201d, the Company had access to a wide range of funding sources through the credit system and the capital markets (bilateral contracts, pool financing with major domestic and international banks, loan contracts with the European Investment Bank (EIB), bond loans and Commercial Papers<span class=\"_ _0\"></span>).Snam\u2019s objective is to maintain a debt structure that is balanced in composition between bond loans and bank credit, and the availability of usable committed bank credit lines, in line with its business profile and the regulatory environment in which Snam operates.At 31 December 2022, Snam had unused committed long-term credit lines for an amount of around 5.9 billion euros, of which (i) syndicated credit lines of 4.65 billion euros (ii) Revolving Credit F<span class=\"_ _0\"></span>acilities (RCF) for a total of 1.2 billion euros (iii) approximately 40 million euros relating to the framework loan signed with the EIB in June 2021. At 31 December 2022, Snam has a Euro Medium T<span class=\"_ _0\"></span>erm Notes (EMTN) programme in place for a maximum total nominal value of 13 billion, used for approximately 9.5 billion euros and a Euro Commercial Paper Programme (E<span class=\"_ _0\"></span>CP) for a maximum total nominal value of 2.5 billion euros, used at 31 December for 1,130 million euros.Snam\u2019s cash and cash equivalents mainly refer to current accounts and bank deposits readily collectable.The Group\u2019s main long-term financial payables include covenants that are typical of international practice, such as negative pledge and pari passu clauses. F<span class=\"_ _0\"></span>ailure to meet these clauses, and the occurrence of other events, for example cross-default events, may result in Snam\u2019s failure to comply and could trigger the early repayment of the relative loan, resulting in additional costs and/or liquidity issues. There are no covenants among commitments that involve compliance with ratios of an economic and/or financial nature. Among the factors that define the risk perceived by the market, creditworthiness, assigned to Snam by rating agencies, plays a decisive role because it influences their ability to access sources of financing and the related economic conditions. A worsening of this creditworthiness could therefore constitute a limitation on access to the capital market and/or an increase in the cost of sources of financing, with consequent negative effects on the Group\u2019s economic situation, equity and financial position.Snam\u2019s long term rating is: (i) Baa2 with negative outlook, confirmed on 06 September 2022 by Moody's Investor Services; (ii) BBB+ with stable outlook, confirmed on 06 February 2023 by Standard &amp; Poor's Global Rating (\u201cS&amp;P\u201d); (iii) BBB+ with stable outlook, confirmed on 16 February 2023 by Fitch Ratings (\u201cFitch\u201d). Snam\u2019s long-term rating by Moody\u2019s, Fitch and Standard &amp; Poor\u2019s is a notch higher than that of Italian sovereign debt. Based on the methodology adopted by Moody's and S&amp;P<span class=\"_ _3\"></span>, the downgrade of one notch from the current rating of the Republic of Italy would lead to a corresponding reduction of Snam\u2019s current rating. In this regard, it should be noted that on 30 September 2022, Moody's confirmed the rating of the Italian Republic, maintaining the negative outlook, which had already been lowered on 5 August 2022; this action had caused Snam's Outlook to be revised to negative on 9 August 2022. On 26 July 2022, S&amp;P revised the Italian Republic's Outlook from positive to stable, with corresponding action on Snam's Outlook on 29 July 2022. The next reviews of the Rating Agencies for the Italian Republic are scheduled for 21 April 2023 for S&amp;P<span class=\"_ _3\"></span>, 12 May 2023 for Fitch, 19 May 2023 for Moody's.The company\u2019s short-term rating, used as part of Snam<span class=\"_ _0\"></span>\u2019s Commercial Paper programme, is P-2 for Moody\u2019s, A-2 for S&amp;P and F2 for Fitch.Although the Snam Group has relations with diverse counterparties with a high credit standing, based on the management policy and ongoing monitoring of their credit risk, the default of a counterparty or the difficulty to liquidate assets on the market could have negative effects on Snam Group\u2019s operations, equity situation and financial position.The table below shows the repayment plan contractually established in relation to the financial payables, including interest payments and other liabilities connected to derivative instruments:Contractual c<span class=\"_ _0\"></span>ash \ue7aeowsBook value as (million euros<span class=\"_ _0\"></span>)T<span class=\"_ _3\"></span>otal \ue7aeows<span class=\"_ _207\"> </span><span class=\"ff68\">2022<span class=\"_ _8c\"> </span>2023<span class=\"_ _8c\"> </span>2024<span class=\"_ _8c\"> </span>2025<span class=\"_ _8c\"> </span>2026<span class=\"_ _12\"> </span><span class=\"ls2b ws2d\">Beyond</span></span>at 31.12.2021Bank loans<span class=\"_ _23e\"> </span>3,695<span class=\"_ _a6\"> </span>3,695<span class=\"_ _2a8\"> </span><span class=\"ff6a\">1,297<span class=\"_ _344\"> </span>457<span class=\"_ _45\"> </span>719<span class=\"_ _344\"> </span>121<span class=\"_ _344\"> </span>120<span class=\"_ _45\"> </span>981</span>Bond loans (*)<span class=\"_ _22d\"> </span>9,138<span class=\"_ _a6\"> </span>9,139<span class=\"_ _2ba\"> </span><span class=\"ff6a\">1,130<span class=\"_ _344\"> </span>879<span class=\"_ _2ba\"> </span>1,191<span class=\"_ _2ba\"> </span>1,339<span class=\"_ _2a8\"> </span>1,250<span class=\"_ _2ba\"> </span>3,350</span>Euro C<span class=\"_ _0\"></span>ommercial Paper -

With regard to this event, the Public Prosecutor at the Court of T<span class=\"_ _0\"></span>eramo immediately opened an investigation into negligence associated with the forest fire. Upon completion, the Prosecutor requested the Snam Rete Gas technicians and technical managers be brought to court. The committal to trial was ordered by the preliminary hearing judge for 3 October 2018. At the first main hearing on 10 January 2019, the presiding member of the bench asked the defence and the Public Prosecutor to comment on moving the proceedings to a single judge proficient in this issue. The parties referred to the decision of the Court, which after a short period in council chambers, passed the proceedings onto a competent single judge. The first main hearing was held on 17 September 2020, at which all parties presented their requests for evidence. In the past hearings, the examination and cross-examination of the witnesses of the Public Prosecutor\u2019s Office took place, and for the continuation of the activities, the Judge adjourned the hearing to March 2023 for the conclusion of the hearing of the technical consultants of the Public Prosecutor\u2019s Office and for the start of the witness examination of the technical consultants of the defence.28.2 <span class=\"_ _34\"> </span>Proceedings with the <span class=\"_ _0\"></span>Autorit\u00e0  di Regolazione per Energia Reti  e Ambiente <span class=\"_ _4\"></span>- ARERA<span class=\"_ _0\"></span> Snam Rete Gas S.p.A. - Investigation into violations on the subject of natural gas metering with regard to Snam Rete Gas S.p.A<span class=\"_ _0\"></span> and request for information Through Resolution VIS 97/11, notified on 15 November 2011, the ARER<span class=\"_ _4\"></span>A started proceedings to look into whether there were any violations with regard to natural gas metering, relating to alleged irregularities in gas metering with reference to 45 systems owned by the distributor; through Resolution 431/2012/S/Gas the proceedings were brought together with other proceedings involving said events contested by the company launched with regard to the distributor involved. Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. has submitted proposals in relation to the alleged conduct. By means of Resolution 332/2015/S/gas, the ARER<span class=\"_ _4\"></span>A declared the proposals to be inadmissible, on the grounds that they would not be adequate to restore the alignment of interests existing before the alleged violations or to eliminate any immediate and direct consequences of these violations. Upon completion of the investigation on 20 October 2017, the ARER<span class=\"_ _4\"></span>A notified the results to Snam Rete Gas, which confirmed the charges made when the proceedings were initiated. The company has requested time for it to formulate its own defence and, to this end, a hearing was called before the board of the Authority on 1 March 2018 during which the defence brief was submitted. After the proceedings, the Authority, although accepting some of the Company's arguments deemed relevant from the perspective of the quantification of the fine, imposed an administrative monetary fine on Snam Rete Gas, through resolution 206/2018/S/gas of 5 April 2018, of 880 thousand. Though it paid the fine, the Company has appealed Resolution 206/2018/S/gas before the Regional Administrative Court of Milan. As a result of the hearing in June 2022, with ruling 2142/2022 published on 29 September 2022, the Regional Administrative Court upheld Snam Rete Gas's appeal insofar as it complained of the excessive duration of the punitive proceedings. ARER<span class=\"_ _4\"></span>A promptly appealed the ruling before the Council of State.Snam Rete Gas S.p.A. - Resolution 9/2014/S/gas \u2013 \u201cLaunch of punitive proceedings against Snam Rete Gas S.p.A. for non-compliance with Resolution 292/2013/R/gas\u201d  With Resolution 9/2014/S/gas the ARER<span class=\"_ _4\"></span>A launched punitive proceedings against Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. for non-compliance with Resolution 292/2013/R/gas.<span class=\"_ _0\"></span>The proceedings aim to ascertain whether or not delays exist in provisions relating to the enactment of amendments to the Network Code established by Resolution 292/2013/R/gas, with regard to settlement. Upon conclusion of the proceedings, with its resolution 853/2017/S/gas, the Authority sentenced Snam Rete Gas to pay a pecuniary fine of 95 thousand since, although it accepted a part of the Company\u2019s arguments which were significant insofar as determining the amount of the fine, it considered that the Company was late in complying with Resolution 292/2013/R/Gas. Though it paid the fine, the Company has appealed Resolution 853/2017/S/gas before the Regional Administrative Court of Milan. The Regional Administrative Court (T<span class=\"_ _0\"></span>AR), with ruling No. 1914/2022, upheld Snam Rete Gas' appeal. The judgment was not appealed within the time limit and therefore became res judicata.Snam Rete Gas S.p.A. - Resolution 250/2015/R/gas, published on 01 June 2015, concerning: \u201cAdoption of measures on the odorising of gasfor domestic use and similar for end users connecteddirectly to the natural gas transportation networks\u201d Through Resolution 250/2015/R/gas, following the ruling of the Milan regional administrative court, the ARER<span class=\"_ _4\"></span>A amended Article 5 of Resolution 602/2013/R/ gas dealing with the obligation of transportation companies to odorise gas for end users connected directly to the transportation network, which, taking into account the categories of use indicated in the T<span class=\"_ _0\"></span>esto Integrato Settlement Gas (TISG), do not use the gas delivered for merely technological purposes. In this regard, the ARER<span class=\"_ _4\"></span>A ordered that the transportation companies should completed the implementation of the adaptation plans by 31 January 2017, after carr<span class=\"_ _4\"></span>ying out a survey of the redelivery points involved and sending the ARER<span class=\"_ _4\"></span>A the adaptation plan, to be updated every six months, with the description of the technical solution identified. Snam Rete Gas has appealed against the above resolution believing that the deadline for implementing the plan can only be decided after the survey. Having carried out the survey, when sending the plan and the subsequent updates Snam Rete Gas once again found that the deadline set by the ARER<span class=\"_ _4\"></span>A with its Resolution 484/2016/E/gas was unreasonable. Consequently, in the appeal with which Snam Rete Gas challenged Resolution 250/2015/R/gas, it also included an appeal for further grounds against Resolution 484/2016/E/gas asking for the resolutions challenged to be suspended. The request was accepted by the Council of State. Following the hearing that was held on 16 January 2019, through ruling no. 869 of 17 April 2019, the Milan Regional Administrative Court accepted the appeal submitted by Snam Rete Gas declaring the unlawfulness of the deadline set by the Authority because it was clearly unreasonable as it does not take into account the complexity of the activities to be carried out by the transportation company and the need to collaborate with end users on whom the burden of guaranteeing the use of gas in safe conditions for the workers involved weighs.Note that through the Ministerial Decree of 18 May 2018 the Minister for Economic Development placed the responsibility of guaranteeing the use of gas in safe conditions on the end users directly connected to the natural gas transportation network, where there is domestic or similar use of gas, even only in part, if combined with technological uses. Following the functional activities to the implementation of the Decree, the end users demonstrated that they guaranteed the safe use of the gas in accordance with the methods laid down by said Decree.As part of the Consultation Document (DCO 203/2019/R/Gas) as preparation for the revision of the regulation on<span class=\"_ _0\"></span> the transportation service quality, ARER<span class=\"_ _4\"></span>A demonstrated it\u2019s intention to: (i) confirm the regulatory framework pursuant to the above Resolution 250/2015/R/ Gas without setting a deadline by which the Plan has to be implemented; and (ii) promote a regulatory amendment aimed at coordinating the regulation with the aforementioned Ministerial Decree. Following on from what the DCO anticipates, through Resolution<span class=\"_ _0\"></span> 554/2019/R/gas, the Authority confirmed the previous regulatory regime (the obligation of the transportation company to take responsibility for the odorising) thereby<span class=\"_ _0\"></span> putting forward the issue of coordination with the obligations imposed by the Decree. Therefore, pending a possible regulatory change, Snam Rete Gas challenged Resolution 554/2019/R/gas The hearing date remains to be set.28.3 <span class=\"_ _34\"> </span>T<span class=\"_ _32\"></span>ax disputes Snam Rete Gas S.p.A. - IMU/T<span class=\"_ _3\"></span>ASI - Municipalities<span class=\"_ _4\"></span> in Northern ItalySome municipalities of northern Italy sent Snam Rete Gas 17 assessment notices for IMU<span class=\"_ _0\"></span>/<span class=\"_ _4\"></span>T<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>SI for the years 2016, 2017 and 2018, which follow on from requests for information for land registry purposes pursuant to Article 1, paragraph 693 of Law 147/2013. The company has made a provision for risks and charges. Stogit S.p.A. - IMUThe Municipality of Bordolano ascertained the IMU position in relation to the building areas owned by the Company in the territory of the same Municipality for the years 2012 to 2015. The amounts assessed by the Municipality with the notices of assessment relating to the tax years 2012, 2013 and 2014 - as redetermined by the Lombardy Regional T<span class=\"_ _0\"></span>ax Commission - were paid by the Company during 2020, pending the related legal proceedings.The assessment notice issued by the Municipality in 2015 is still sub iudice in first instance.With reference to the subsequent years 2016 - 2017 - 2018, the Company has already adjusted its payments to the higher value assessed by the Municipality.Snam S.p.A. - Questionnaire Q00017/2020 on V<span class=\"_ _3\"></span>A<span class=\"_ _3\"></span>T On 13 February 2020, the Inland Revenue ser<span class=\"_ _4\"></span>ved Snam a V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T questionnaire requesting the reasons for the tax amnesty made in 2016 with reference to the years 2012, 2013, 2014 and 2015. In particular<span class=\"_ _0\"></span>, in 2016, the Company submitted supplementary declarations for the years 2012 to 2014 to acknowledge that, starting in 2012, it was carrying out a new activity of granting loans and that<span class=\"_ _4\"></span>, in relation to this activity, the Company intended to avail itself of the optional separation of activities for V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T purposes pursuant to art. 36, paragraph 3 of Italian Presidential Decree no. 633/1972. As regards 2015, the relevant annual declaration was submitted within the ordinary time limits and an amicable settlement was made to remedy certain irregularities (also related to the keeping of separate accounts) that had affected the correct monthly settlements. Following a preliminary investigation, on 21 December 2020, the Revenue Agency ser<span class=\"_ _4\"></span>ved an order to appear for the establishment of the cross-examination of the years 2012-2013-2014-2015, in order to better verify whether the Company actually behaved \" ex ante\" in this sense.The Company, in order to avoid a long and complex dispute, on 25 March 2021 and 30 November 2022, following the acceptance of the assessment, paid the agreed amounts.28.4 <span class=\"_ _34\"> </span>Other proceedingsSnam Rete Gas S.p.A. - Regulation criteria for natural gas transmission and dispatching tariffs for the period 2010-2013  By ruling No. 2888/2015, the Council of State rejected the appeal filed by ARER<span class=\"_ _4\"></span>A asking it to overturn ruling No. 995/2013 by the Regional Administrative Court of Milan, which voided the provisions of resolutions ARG/gas/184/09, 192/09, 198/09 and 218/10 concerning natural gas transportation and dispatching rates for the 2010-2013 period, specifically with regard to the commodity/capacity allocation, the reform of the entry/exit model and gas for consumption by compression stations (self- consumption<span class=\"_ _0\"></span>).By way of Resolution 428/2015/C/gas, ARERA resolved to appeal for revocation on the grounds of an error of fact against the aforementioned ruling, an appeal which was subsequently withdrawn on 29 March 2018 due to the lack of interest in continuing the proceedings. At the same time, the Authority complied with the aforementioned rulings by way of Resolution 550/2016/R/gas whereby, having reformed the rules on self-consumption, it justified its confirmation of the remaining tariff criteria also in light of the consultations carried out. Given the confirmatory nature of the aforementioned<span class=\"_ _4\"></span> resolution, the original appellant contested for compliance with the aforementioned rulings and a declaration of the nullity of Resolution 550/2016/R/gas. By ruling no. 494/2017,<span class=\"_ _4\"></span> the Milan Regional Administrative Court partially upheld the appeal with specific reference to the issue of the commodity/capacity allocation, finding that the contested Resolution complied inaccurately and partially with ruling No. 995/2013 and that, therefore, the Authority should carr<span class=\"_ _4\"></span>y out an additional assessment of the effects of the choices made. Ruling No. 494/2017 was challenged by the appellant, as well as incidentally by ARER<span class=\"_ _4\"></span>A. In judgement no. 1840/2018 of 23 March 2018, the Council of State, in partial acceptance of the Authority\u2019s cross-appeal, dismissed the action of nullity for breach of judgement filed by the appellant at first instance and ordered the conversion of the proceedings into an ordinary judgement of annulment<span class=\"_ _4\"></span>. The appellant consequently resumed the proceedings before the Milan Regional Administrative Court.It should also be noted that in its recent ruling no. 301/2021, the Milan Regional Administrative Court partially annulled, on partly similar grounds, ARERA Resolution no. 575/2017/R/gas relating to the 2018- 2019 transitional regulatory period. In particular, the caesuras at the 90:10 ratio between the capacity/commodity components were confirmed. In addition, the Regional Administrative Court held that the aforementioned resolution should be annulled in so far as it provides for the determination of unit transport costs on the basis of calculations of gas flows (so-called flows and counter-flows<span class=\"_ _0\"></span>). The judgement was appealed by the Authority. The Regional Administrative Court, in ruling no. 219/2022, upheld a similar appeal in relation to the tariff regime for the 2014-2017 thermal years set forth in ARER<span class=\"_ _4\"></span>A Resolution no. 514/2013/R/gas, in relation to which the terms for any appeal are pending. The ruling, which was appealed by ARERA<span class=\"_ _4\"></span>, was confirmed by ruling No. 8523/2022 of the Council of State.Lastly, it should be noted that the judgements of the Milan Regional Administrative Court (T<span class=\"_ _0\"></span>AR) no. 440/2020 and no. 33/2021 partially annulled the aforementioned Resolution no. 575/2017/R/gas, as well as Resolution no. 114/2019/R/gas (2020-2023 tariff criteria) insofar as they do not provide for a degressive tariff in favour of large gas consumers in implementation of specific primary legislation. Both<span class=\"_ _4\"></span> judgements were appealed by the Authority; the discussion of the appeals before the Council of State was held in April 2022, which was followed by Judgements Nos. 6096/2022 and 6098/2022 rejecting the Authority's respective appeals. In compliance with the aforementioned rulings, ARER<span class=\"_ _4\"></span>A adopted DCO 41/2023/R/gas containing the Authority's guidelines in relation to cost<span class=\"_ _0\"></span>-efficiency measures in the transportation tariff<span class=\"_ _4\"></span> system for subjects with higher natural gas consumption.In all the above cases, the disputed profiles do not affect the revenues recognised to the transport companies.Stogit S.p.A. - <span class=\"_ _0\"></span>Appeals Coordination Environmental Committee (Ricorsi Coordinamento Comitato <span class=\"_ _0\"></span>Ambientalisti) With the Presidential Decree of 16 September 2019, the binding opinion published by the Council of State on 27 June 2019, by which the appeals filed by the Appeals Coordination Environmental Committee plus others were accepted, was implemented. In that Presidential Decree it is stated that: (i) on account of the failure to file the documents relating to the environmental impact assessment in the municipalities of Azzanello and Verolavecchia, the VIA decree issued<span class=\"_ _0\"></span> in 2009 for the construction of the new storage facility at Bordolano is annulled, without prejudice to the provisions contained therein, only in so far as it expresses a favourable opinion on environmental compatibility; (ii) the decree of the Ministry of Economic Development of 28 December 2011 (approval of the change in the work programme of the \"Bordolano Storage\" concession<span class=\"_ _0\"></span>) is annulled, as well as (iii) the measures of the Ministry of the Environment (prot<span class=\"_ _4\"></span>. no. 18804 of 8 August 2013 and prot. no.14583 of 16 May 2014), again on the subject of VIA<span class=\"_ _4\"></span>, without prejudice to the continuing validity of the prescriptions contained therein, to protect public safety and security, which are in no way overturned by the annulment ruling. The Council of State also established the reopening of the VIA procedure and the Ministry of Environment promptly reopened the terms of the VIA (with note DV<span class=\"_ _0\"></span>A U28389 of 29 October 2019) limited to the municipalities of Azzanello and Verolavecchia only; of these, only the municipality of V<span class=\"_ _3\"></span>erolavecchia submitted comments, to which were added those of other parties. The proceedings are currently pending before the T<span class=\"_ _0\"></span>echnical Commission for Environmental Impact Assessment ( Commissione T<span class=\"_ _0\"></span>ecnica per la Valutazione di Impatto<span class=\"_ _0\"></span> Ambientale) and Stogit has provided all the technical clarifications in response to the comments submitted. It should be added that the MED y note U.0025890 of 22 November 2019, issued a measure pursuant to Article 29, paragraph 3 of<span class=\"_ _0\"></span> Legislative Decree no. 152/2006, which allows the continuation of storage activities at the Bordolano plant pending the completion of the VIA. There are grounds to believe that there is a remote risk that the positive environmental impact assessment will not be confirmed; however<span class=\"_ _0\"></span>, also in light of the time that has elapsed, the possibility that the VIA will be confirmed by the Ministry of the Environment with the addition of prescriptive conditions with which Stogit will have to comply can be assessed as probable.Action brought by the Forum <span class=\"_ _0\"></span>Ambientalista and <span class=\"_ _0\"></span>Action brought by WWF Italia - <span class=\"_ _0\"></span>Associazione Salviamo l\u2019Orso marsicano OdV against the integrated environmental authorisation for the new Sulmona power stationOn 2 June 2021, the Environmental Forum - which claims to be an environmental protection association - lodged an appeal with the Regional Administrative Court of Lazio for the annulment of Decree no. 000086 of 11.03.2021 of the Ministry for Ecological Transition concerning the issue of the integrated environmental authorisation (AIA) for the operation of the gas compression station of the company Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. located in Sulmona (AQ) - (ID 7015/9997) as well as all the prior<span class=\"_ _0\"></span>, consequential or in any case related deeds. The applicant claims that its reasons are based on: i) the seismic risk to which the works of Snam Rete Gas are allegedly subject; ii) failure to conduct a preliminary investigation into emissions and failure to take account of their effects on animals and plants in the area concerned; iii) failure to carry out a strategic environmental assessment (SE<span class=\"_ _4\"></span>A) as a precondition for the issue of the AIA; iv) shortcomings in the preliminar<span class=\"_ _4\"></span>y investigation procedure leading to the issue of the AIA. No interlocutor<span class=\"_ _4\"></span>y application was filed; at the hearing at the end of January 2023, the case was retained for decision. In an appeal to the President of the Republic dated 6 August 2021, the Italian Association for the Word Wife Found of Nature (WWF Italia Onlus) and the association Salviamo l'orso Bruno Marsicano_ODV also applied for the annulment of Decree No 0000086 of 11.03.2021 of the Ministry of Ecological Transition, which constitutes the IEA for the new Sulmona power station. The reasons given are: i) the ineffectiveness of the EIA which allegedly failed in 2016; ii) the excess of power in having ignored the observations of the Municipality of Sulmona and of the Maiella National Park, the Abruzzo National Park and the Monte Genzana Alto Gizio Regional Nature Reserve (iii) failure to take adequate account of the seismic risk; (iv) failure to take account of the public\u2019s comments; (v) infringement of the law and misuse of powers on account of failure to carry out preliminar<span class=\"_ _4\"></span>y investigations into atmospheric emissions and the impact on the climate; (vi) infringement of Directive 42/2001 EC by failing to carry out a strategic environmental assessment. Following an objection by Snam Rete Gas, the appeal was resumed before the Lazio Regional Administrative Court by the appellants on 3 November 2021.

The Plans, intended for the Snam CEO and other beneficiaries, identified as those who hold positions with a greater impact on company results or with strategic importance for achieving Snam\u2019s multi-year targets, includes three cycles of the annual assignment of three-year targets (the so-called rolling plan) for the years 2017, 2018, 2019 and for the years 2020, 2021 and 2022. At the end of the three-year performance period, if the underlying conditions of the plan are met, the beneficiary shall have the right to receive Company shares free of charge. A maximum number of 3,500,000 shares will service the Plans for each three-year c<span class=\"_ _4\"></span>ycle of the Plan. The 2017-2019<span class=\"_ _0\"></span> Plan ended in 2022, at the expiry of the Vesting P<span class=\"_ _0\"></span>eriod relating to the last allocation of 2019, while the 2020-2022 Plan will end in 2025, at the expiry of the Vesting P<span class=\"_ _0\"></span>eriod relating to the last allocation of 2022.Under the 2017-2019 Plan, a total of 5,385,372 shares were granted, of which 1,368,397 shares valid for the 2017 allocation (allocated for 1,511,461 shares in July 2020, at the end of the vesting period), 2,324,413 shares valid for the 2018 allocation (allocated for 2,441,742 in July 2021, at the end of the vesting period) and 1,692,562 shares valid for the 2019 allocation. The unit fair value of the share, determined by the stock market price of the Snam share<span class=\"_ _0\"></span> on the grant dates, is equal to 3.8548 and 3.5463 and 4.3522 euros per share for the 2017, 2018 and 2019 grants, respectively.<span class=\"_ _0\"></span> Against the 2020-2022 Plan, valid for the years 2020 and 2021, a total of 2,523,850 shares were allocated, of which 1,277,996 shares valid for the 2020 allocation, 1,245,854 shares valid for the 2021 allocation and 1,032,626 shares valid for the year 2022. The unit fair value of the share, determined by the stock market price of the Snam share on<span class=\"_ _0\"></span> the grant dates (so-called grant date), is equal to 4.441 and 4.559 euros per share for the year 2020, 5.104, 4.778 and<span class=\"_ _0\"></span> 5.014 euros per share for 2021 and 4.900 and 4.146 per share for 2022.The cost for the Long-<span class=\"_ _0\"></span>T<span class=\"_ _0\"></span>erm Share-Based Incentive Plan, measured as the staff costs component, amounts to 6 million euros (8 million euros in 2021) with an opposing entry in shareholder equity reser<span class=\"_ _4\"></span>ves.

In 2022, the free allocation for the Snam Group was 154,657 allowances, an increase of 9.8 % compared to 2021, due to the new rules introduced by the aforementioned legislation for the fourth ETS period. In FY 2022, dioxide carbon emissions of Snam Group facilities covered by the ETS were overall greater than the emission allowances allocated. Compared to approximately 0.93 million tonnes of carbon dioxide emitted into the atmosphere, a deficit has therefore been recorded of approximately 0.77 million tonnes. The deficit was offset by the quotas purchased by the various companies, with an approximately cost of 57.4 million euros recognised in \u201cOther operating costs and expenses\u201d. There are no costs for Renovit (TEP), because the purchase of CO quotas is borne by the company to which the 2plant supplies energy net of the quotas in the hands of Renovit (TEP) for feeding electricity into the grid. These amounted to about 4,300 units, with a countervalue of about 0.3 million euros.The increase in purchased CO allowances is due to the increase in emissions resulting from the increase in gas 2consumption due to the increase in regasified, stored gas and to transport more natural gas from the South to the North of Italy.The increase in the number of CO allowances purchased and the increase in purchase prices led to higher costs than in the 2previous year<span class=\"_ _0\"></span>.31  <span class=\"_ _13\"> </span>DEPRECIA<span class=\"_ _3\"></span>TION,<span class=\"_ _3\"></span> AMORTISA<span class=\"_ _1\"></span>TION <span class=\"_ _0\"></span>AND<span class=\"_ _0\"></span> IMP<span class=\"_ _32\"></span>AIRMENT LOSSES <span class=\"_ _0\"></span>ON PROPERTY<span class=\"_ _28\"></span>, PLANT<span class=\"_ _30\"></span>,<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>EQUIPMENT AND<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>INT<span class=\"_ _32\"></span>ANGIBLE ASSETS(million euros<span class=\"_ _0\"></span>)<span class=\"_ _361\"> </span>2021<span class=\"_ _eb\"> </span>2022Depreciation of property, plant and equipment<span class=\"_ _30d\"> </span>709<span class=\"_ _161\"> </span>747Amortisation of intangible assets<span class=\"_ _22b\"> </span>100<span class=\"_ _161\"> </span>120T<span class=\"_ _3\"></span>otal amortisation/depreciation<span class=\"_ _36e\"> </span>809<span class=\"_ _161\"> </span>867Impairment losses on property, plant and equipment and intangible assets<span class=\"_ _13c\"> </span>11<span class=\"_ _101\"> </span>23T<span class=\"_ _3\"></span>otal impairment losses<span class=\"_ _27b\"> </span>11<span class=\"_ _101\"> </span>23TO<span class=\"_ _0\"></span>T<span class=\"_ _3\"></span>AL DEPRECIA<span class=\"_ _3\"></span>TION, AMORTISATION AND IMP<span class=\"_ _3\"></span>AIRMENT LOSSES<span class=\"_ _36f\"> </span>820<span class=\"_ _161\"> </span>890For more details about amortisation, depreciation and impairment losses, please see Note 8 \u201cProperty, plant and equipment\u201d, and Note 9 \u201cIntangible assets and goodwill\u201d.An analysis of amortisation, depreciation and impairment losses by business segment can be found in Note 35 \u201cInformation by business segment\u201d.32  <span class=\"_ _13\"> </span>NET FINANCIAL<span class=\"_ _0\"></span> EXPENSE(million euros<span class=\"_ _0\"></span>)<span class=\"_ _361\"> </span>2021<span class=\"_ _eb\"> </span>2022- Interest income and other financial inc<span class=\"_ _0\"></span>ome on short<span class=\"_ _0\"></span>-term financial assets<span class=\"_ _ac\"> </span>(15)<span class=\"_ _80\"> </span>(3)- Interest income on long-t<span class=\"_ _0\"></span>erm financial receivables<span class=\"_ _108\"> </span>(14)<span class=\"_ _e6\"> </span>(9)- Other financial income<span class=\"_ _2a3\"> </span>(3)<span class=\"_ _16a\"> </span>(25)TO<span class=\"_ _0\"></span>T<span class=\"_ _3\"></span>AL FINANCIAL INCOME <span class=\"_ _2b1\"> </span>(32)<span class=\"_ _16d\"> </span>(37)- Interest expense and other financial expenses on bond loans<span class=\"_ _1e5\"> </span>127<span class=\"_ _161\"> </span>148- Fees on loans and bank credit lines<span class=\"_ _33b\"> </span>12<span class=\"_ _e6\"> </span>10- Interest expense on credit facilities and loans due to banks and other lenders<span class=\"_ _1b7\"> </span>7<span class=\"_ _101\"> </span>17Charges related to gross financial debt<span class=\"_ _370\"> </span>146<span class=\"_ _161\"> </span>175- Accretion discount (*)<span class=\"_ _371\"> </span>5<span class=\"_ _101\"> </span>12- Other financial expense<span class=\"_ _27b\"> </span>3<span class=\"_ _101\"> </span>15T<span class=\"_ _3\"></span>otal financial expenses incurred during the year<span class=\"_ _1fb\"> </span>154<span class=\"_ _161\"> </span>202- Share of capitalised financial expenses<span class=\"_ _259\"> </span>(20)<span class=\"_ _16a\"> </span>(25)TO<span class=\"_ _0\"></span>T<span class=\"_ _3\"></span>AL FINANCIAL EXPENSES <span class=\"_ _1ab\"> </span>134<span class=\"_ _161\"> </span>177TO<span class=\"_ _0\"></span>T<span class=\"_ _3\"></span>AL NET FINANCIAL EXPENSES<span class=\"_ _33b\"> </span>102<span class=\"_ _161\"> </span>140(*) <span class=\"_ _29\"> </span>The it<span class=\"_ _0\"></span>em reflects the increase in the provisions for risks and charges and the liabilities for employee benefits, which are shown at their present value in Not<span class=\"_ _0\"></span>e 19 \u201cProvisions for risks and charges\u201d and Note 21 \u201cLiabilities for employee benefits\u201d.Interest income on long-term financial receivables is mainly related to the pro-rata contribution from the OL<span class=\"_ _32\"></span>T Shareholder Loan (9 million euros).

This last segment, due to exceeding the materiality thresholds of IFRS 8, also confirmed in the Plan period, from 2022 constitutes an operating segment subject to separate reporting.   The 'Other segments', not subject to separate reporting, mainly include the sustainable mobility business, an activity<span class=\"_ _0\"></span> that is being repositioned within the Gas Infrastructures business insofar as it is no longer focused solely on the automotive sector<span class=\"_ _0\"></span>, but is oriented towards the construction of mid-stream infrastructures dedicated to heavy transport, shipping and railways. Other unallocated amounts essentially relate to head office activities of Snam corporate and insurance captives.In order to assess the performance of the operating segments, Snam management mainly analyses adjusted EBITDA (net of any non-recurring costs or revenues, or costs or revenues resulting from events or transactions that are not representative of normal business activity) and adjusted EBIT<span class=\"_ _3\"></span>, for which a reconciliation with the related reported values is provided.In addition to the above measures, the Executive Board regularly analyses revenues and investments for each business.In order to allow for a better reconciliation with what is represented for management purposes, the representation of revenues has been modified, distinguishing \u201cRegulated revenues\u201d, relating to services subject to regulation by the ARER<span class=\"_ _4\"></span>A authority, from \u201c<span class=\"_ _0\"></span>Other revenues\u201d and \u201cOther income\u201d not subject to such regulation, instead of the distinction<span class=\"_ _0\"></span> between \u201cRevenues from ordinary operations\u201d and \u201cOther revenues and income\u201d. 41 <span class=\"_ _d\"> </span>Segment reported separately as a business subject to specific regulation, even if the materiality thresholds of IFRS 8 are not exceeded.

All the transactions carried out were in the interest of the companies of the Snam Group.Pursuant to the provisions of the relevant legislation, the Company has adopted internal guidelines to ensure that transactions carried out by Snam or its subsidiaries with related parties are transparent and correct in their substance and procedure.  Directors and statutory auditors declare potential interests that they have in relation to the Company and the Group every six months, and/or when changes in said interests occur; they also inform the Chief Executive Officer (or the Chair<span class=\"_ _0\"></span>, in the case of the Chief Executive Officer\u2019s interests), who in turn informs the other directors and the Board of Statutory Auditors, of individual transactions that the Company intends to carry out and in which they have an interest.Snam is not subject to any direction or coordination activities.

The effectiveness of the Guarantee - pursuant to Article 15(9) of the Decree - is subject to the issuance of an ad hoc decree of the Ministry of Economy and Finance, in agreement with the Minister of Economic Development, adopted on the basis of the preliminary investigation submitted by SACE.

The same annex shows the changes in the scope of consolidation at 31 December 2022 compared to 31 December 2021. For further details on the acquisition of controlling interests, for which the conditions for the application of IFRS 3 exist, please refer to the section \u201cBusiness combinations\u201d. All the financial statements of the companies included in the scope of consolidation are expressed in euro, adjusted, where necessary, to make them consistent with the accounting principles applied by the Parent Company<span class=\"_ _0\"></span>.<span class=\"ls0\"> </span>Fully consolidated subsidiariesThe Group defines another entity as a subsidiary when it:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">has the power to make decisions concerning the investee entity;</span>\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">is entitled to receive a share of or is exposed to the variable profits and losses of the investee entity;</span>\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">is able to exercise power over the investee entity in such a way as to affect the amount of its economic returns.</span>Figures relating to subsidiaries are included in the consolidated financial statements, based on standardised accounting principles, from the date on which the Company assumes direct or indirect control over them until the date on which said control ceases to exist. The assets, liabilities, income and expenses of consolidated companies are fully incorporated line-by-line in the consolidated financial statements (full consolidation method). Unrealised gains from transactions between consolidated companies are derecognised, as are receivables, payables, income, expenses, guarantees, commitments and risks between consolidated companies. The portion pertaining to the Group of unrealised gains with companies valued using the equity method is derecognised. In both cases, intragroup losses are not derecognised because they are considered to represent the impairment loss on the transferred asset.Changes in equity investments held directly or indirectly by the Company in subsidiaries that do not result in a change in the qualification of the investment as a subsidiary are recorded directly in equity as transactions with shareholders. The book value of the equity attributable to Parent company shareholders and non-controlling interests are adjusted to reflect the change in the equity investment ownership. The difference between the book value of minority interests and the fair value of the consideration paid or received is recorded directly under equity attributable to Parent company shareholders.Otherwise, the selling of interests entailing loss of control requires the posting to the income statement of: (i) any capital gains or losses calculated as the difference between the consideration received and the corresponding portion of shareholders\u2019 equity transferred; (ii) the effect of the alignment to the fair value of any residual equity investment maintained; (iii) any amounts posted to other components in the comprehensive income statement relating to the former subsidiary that will be reclassified to the income statement<span class=\"_ _4\"></span>. The fair value of any equity investment maintained<span class=\"_ _0\"></span> at the date of loss of control represents the new reference value for the successive valuation of the equity investment according to the applicable valuation criteria.Associates and joint ventures accounted for using the equity methodAn associate is an investee in which the Group has significant influence, i.e., the power to participate in determining the financial and operating policies of the associate company, without, however<span class=\"_ _0\"></span>, having control or 2joint control over it. It is assumed that the investor has significant influence (unless there is proof to the contrary) which is presumed to exist when the investment held is at least 20% of the exercisable voting rights.A joint venture is a joint arrangement in which the parties that hold joint control have rights to the net assets subject to the arrangement and, therefore, have an interest in the jointly controlled corporate vehicle.Equity investments in associates and joint ventures are measured using the equity method, whereby the investments are initially recognised at cost and subsequently adjusted to take account of:(i) <span class=\"_ _34\"> </span>the investor<span class=\"_ _4\"></span>\u2019s share in the economic results of the investee after the acquisition date;(ii) <span class=\"_ _e\"> </span>the investor\u2019s share of the other components in the comprehensive income statement of the investee.Dividends distributed by the investee are recognised net of the book value of the equity investment. For the purposes of applying the equity method, the adjustments provided for the consolidation process are taken into account (see also the previous point on fully consolidated subsidiaries).The sale of investment that results in loss of joint control or significant influence over the investee determines the recognition of the following in the income statement: (i) any capital gains or losses calculated as the difference between the consideration received and the corresponding fraction of the book value of the investment sold; (ii) the effect of the alignment to the fair value of any residual equity investment maintained; (iii) any amounts posted to other components in the comprehensive income statement relating to the investee entity that will be reclassified to the income statement. The value of any equity investment maintained, aligned with the relative fair value at the date of loss of joint control or significant influence, represents the new reference value for the successive valuation according to the applicable valuation criteria. If there is objective evidence of impairment, the Group performs an impairment assessment  by comparing the book value with the related recoverable amount and recognises the difference in the income statement under \u201cShare of profit or loss of investments accounted for using the equity method\u201d. If the Group\u2019s share of the loss exceeds the book value of the investment, the latter is written 2 <span class=\"_ _48\"> </span>Joint control is the contractual sharing of control pursuant to an agreement, which exists only where the unanimous consent of all the parties that share power is required for decisions relating to significant activities.off and any excess is recognised in a specific provision, if the investor is obliged to meet the legal or constructive obligations of the investee or otherwise cover its losses. When the reasons for the impairment losses no longer apply, equity investments are revalued up to the amount of the impairment losses entered, with the effect posted to the income statement under the above item.The parent company\u2019s share of any losses of the investee company, greater than the investment\u2019s book value, is<span class=\"_ _0\"></span> recognised in a special provision to the extent that the parent company is committed to fulfilling its legal or implied obligations to the investee, or<span class=\"_ _0\"></span>, in any event, to covering its losses.<span class=\"ls0\"> </span>Business combinationsBusiness combinations are transactions with which the group acquires control of a business. T<span class=\"_ _0\"></span>o determine whether a particular set of acquired assets and activities meets the definition of a \u201cbusiness\u201d, the Group examines whether that set comprises, at least, a production factor and a substantial process and whether it has the ability to generate production. Business combinations are accounted for by applying the acquisition method, whereby the consideration transferred at the date of acquisition of control is equal to the fair value of the assets transferred, the liabilities incurred or taken on, and any equity instruments issued.<span class=\"_ _0\"></span> The consideration transferred also includes the current value of any deferred fixed payments and the fair value of any contingent considerations (e.g earn-outs). If the<span class=\"_ _0\"></span> contingent consideration meets the definition of an equity instrument, it is classified as shareholders\u2019 equity and is not measured thereafter<span class=\"_ _0\"></span>. Other contingent considerations are recognised as a liabilities and are measured at fair value at each financial year-end; changes in fair value are<span class=\"_ _0\"></span> recognised in the income statement.Costs directly attributable to the transaction, other than those related to the issue of debt or equity instruments, are recognised in the income statement when they are incurred.The shareholders\u2019 equity of these associate companies is determined by attributing to each asset and liability its fair value at the date of acquisition of control. If positive, any difference from the consideration transferred is posted to the asset item \u201cGoodwill\u201d; if negative, it is posted instead to the income statement.Where total control is not acquired, the share of equity attributable to minority interests is determined based on the share of the current values attributed to assets and liabilities at the date of acquisition of control, net of any goodwill (the \u201cpartial goodwill method\u201d). Alternatively, the full amount of the goodwill generated by the acquisition is recognised, therefore also taking into account the portion attributable to minority interests (the \u201cfull goodwill method\u201d). In this case, non-controlling interests are expressed at their total fair value, including the attributable share of goodwill. The choice of how to determine goodwill (Partial goodwill method or full goodwill method) is based on each individual business combination transaction.If control is assumed in successive stages, the consideration transferred is determined by adding together the fair value of the equity investment previously held in the acquired company and the amount paid to acquire the additional equity investment. The difference between the fair value of the previously held equity investment (redetermined at the time of acquisition of control) and the relative book value is posted to the income statement. Upon acquisition of control, any components previously recognised under other components in the comprehensive income statement are posted to the income statement or to another item of shareholders\u2019 equity, if no provisions are made for classification in the income statement.When the values of the assets and liabilities of the acquired entity are determined provisionally in the financial year in which the business combination is concluded, the figures recorded are adjusted, with retroactive effect, no later than 12 months after the acquisition date, to take into account new information about facts and circumstances in existence at the acquisition date.Business combinations involving entities under joint controlBusiness combinations involving companies that are definitively controlled by the same company or companies before and after the transaction, and where such control is not temporary, are classed as \u201cBusiness combinations of entities under common control\u201d, whose accounting is not specifically disclosed in IFRSs.  In the absence of a reference accounting standard, the selection of an accounting standard for such transactions, for which a significant influence on future cash flows cannot be established, is guided by the principle of prudence, which leads to the application of the criterion of continuity of values of the net assets acquired. The assets are measured at the book values from the financial statements of the companies being acquired (or the vendor company) before the transaction or<span class=\"_ _0\"></span>, alternatively, at the values from<span class=\"_ _0\"></span> the consolidated financial statements of the common ultimate parent.With regard to the sale of business, the treatment of the difference between the contractually defined consideration and the carrying amounts of the transferred business is differentiated depending on the entities involved in the transfer<span class=\"_ _0\"></span>.With regard to contributions involving businesses under common control, on the other hand, irrespective of the pre-existing investment relationship, the transferee entity recognises the transferred business at its historical carrying value, increasing its own equity by an equal amount; the transferring entity shall recognise the investment in the transferee entity at an amount equal to the increase in the latter\u2019s shareholders\u2019 equity. This accounting treatment refers to the proposal by Assirevi in the Preliminary Guidelines on IFRS (OPI No. 1 Revised) - \u201c<span class=\"_ _3\"></span>Accounting treatment of business combinations of entities under common control in the separate and consolidated financial statements\u201d issued in October 2016.<span class=\"ls0 ws0\"> </span>Accounting treatment of put options written on the shares of subsidiariesTherefore, if the Group does not have the unconditional right to avoid delivery of cash or other financial instruments when a put option on shares in subsidiaries is exercised, a financial liability equal to the current value of the option exercise price is recognised and subsequent changes in the financial liability are recognised in the income statement. The same accounting treatment is applicable when, in addition to a put option, there is also the simultaneous presence of a symmetrical call option, the so-called \u201csymmetrical put and call options related to non-controlling interest\u201d.Snam considers that shares subject to put options (or symmetrical put and call options) have already been acquired by the Group, in cases where the economic benefits and risks associated with the actual ownership of the shares do not remain with the minority shareholders; therefore, in such circumstances, it does not recognise minority interests in the consolidated financial statements.5.2 <span class=\"_ _82\"> </span>Property<span class=\"_ _3\"></span>, plant and equipment  Recognition and measurement of property assetsProperty, plant and equipment are measured at cost, less accumulated depreciation and impairment losses. When a significant period of time is needed before the asset is ready for use, financial expenses incurred during the asset preparation period are also capitalised in the cost of the asset.If there are current obligations for dismantling and removal the assets and restore the sites, the book value includes the estimated (discounted) costs to be incurred at the time that the structures are abandoned, recognised as a contra-entry to a specific provision. The accounting treatment for revisions in these cost estimates, the passage of time and the discount rate are indicated in the Note 5.9 \u201cProvisions for risks and charges, contingent liabilities and contingent assets\u201d.Subsequent costs of improvements, upgrades and transformations to/ of property, plant and equipment are capitalised when it is likely that they will increase the future economic benefits expected. Costs are also capitalised when related to items purchased for security or environmental reasons which, although not directly improving the future economic benefits of existing assets, are necessary to carr<span class=\"_ _4\"></span>y out the company\u2019s operations.Property, plant and equipment includes:  (i) <span class=\"_ _16\"> </span>with regard to natural gas transportation, the value relating to the quantities of natural gas injected to bring natural gas pipelines into service. The valuation is carried out using the weighted average purchase price method. Specifically, the component of this quantity that can no longer be extracted (the \u201cinitial line pack\u201d) is depreciated over the useful life of the plant to which it refers. On the contrary, the commercial component, which is eventually transferable to the market or can be put to alternative uses (the so-called \u201cOperating line pack\u201d), is not subject to depreciation, since by its nature it cannot depreciate; (ii) <span class=\"_\"> </span>in the context of natural gas storage, the part of the gas injected into the storage wells as cushion gas.Recognition and measurement of leased assetsA contract is or contains a lease if it gives an entity the right to control the use of an identified asset for a certain period of time in exchange for a fee. For all leases that run for more than 12 months, relating to non- low value 3assets, the following elements are recognised in the balance sheet at the effective date, i.e. when the asset is available for use:(i) an asset, under Property, plant and equipment, representing the right to use the asset, and (ii) a financial liability, representing the obligation to make<span class=\"_ _0\"></span> 3 <span class=\"_ _48\"> </span>The Group considers low-value assets to be all assets worth 25 thousand euros or less. the payments under the contract (also referred to as the \u201clease liability\u201d). In determining the duration of the lease, the group considers the non-cancellable period of the contract and, when it believes there is reasonable certainty, also the additional periods for the exercise of renewal options or the non-exercise of early termination options provided in the contract.Liabilities for leases are recognised initially at an amount equal to the current value of the following lease payments not yet made at the lease commencement date:  (i) <span class=\"_ _16\"> </span>fixed (or substantially fixed) payments, net of any incentives to be received; (ii) <span class=\"_\"> </span>variable payments that depend on trends in rates or indices;(iii) estimated future payments for any residual value guarantees, for the exercise of the purchase option and for any penalties related to the early termination of the contract, if the group considers the exercise of such options to be reasonably certain.The current value of the payments is calculated using a discount rate equal to the group\u2019s marginal borrowing rate taking into account the frequency and duration of payments under the lease agreement.Subsequent to initial recognition, the lease liability is measured at amortised cost and is redetermined, against the book value of the right<span class=\"_ _0\"></span>-of-use asset, when there is a change in the lease payments due as a result of: (i) <span class=\"_ _16\"> </span>contract renegotiations;(ii) <span class=\"_\"> </span>changes in rates or indices;  (iii) changes in measurement made regarding the exercise of contractually-provided options (e.g. purchase of the leased asset or the extension or early termination of the contract).The right<span class=\"_ _0\"></span>-of-use asset is initially recognised at cost, determined as the sum of the following components: (i) <span class=\"_ _16\"> </span>the initial amount of the finance lease liability; (ii) <span class=\"_\"> </span>the initial direct costs incurred by the lessee; (iii) any payments made on or before the lease commencement date, net of any incentives received by the lessor; (iv) the best estimate of the costs that the group expects to incur for the dismantling and removal of the asset and for the possible restoration of the site (i.e. the costs for restoring the asset to the conditions established in the contract).

They are recognised at cost net of amortisation and any accumulated impairment losses.Goodwill arising from the acquisition of subsidiaries is measured at cost less impairment losses cumulated.T<span class=\"_ _0\"></span>echnical development costs are capitalised as intangible assets when: (i) the cost attributable to the intangible asset can be reliably determined; (ii) there is the intent, availability of financial resources and technical capability to make the asset available for use or sale; and (iii) it can be shown that the asset is capable of producing future economic benefits.Alternatively, costs for the acquisition of new knowledge or discoveries, investigations into products or alternative processes, new techniques or models, or the design and construction of prototypes, or incurred for other scientific research or technological developments, which do not meet the conditions for capitalisation are considered current costs and charged to the income statement for the period in which they are incurred.The book value of the storage concessions represents the reserves of natural gas in the fields (so-called cushion gas), which does undergo depreciation, because: (i) <span class=\"_ _16\"> </span>the volume of this gas is not changed by the storage activity; (ii) <span class=\"_\"> </span>the economic value of the gas that can be recovered at the end of the concession, in accordance with the provisions of the Ministerial Decree of 3 November 2005 \u201cCriteria for determining an adequate consideration for the remuneration of assets allocated to a concessionaire for the storage of natural gas\u201d of the Ministry of Productive Activities (MAP), is not less than the value recorded in the financial statements.Amortisation of intangible assets with finite useful life Intangible assets with a finite useful life are amortised systematically over their useful life, which is understood to be the period of time in which it is expected that the company may use the asset.The table below shows the annual depreciation rates used for the year in question, broken down into homogeneous categories, together with the relevant period of application:Annual economic<span class=\"_ _0\"></span>-technic<span class=\"_ _0\"></span>al depreciation rat<span class=\"_ _0\"></span>e (%) Storage concessions<span class=\"_ _163\"> </span><span class=\"ff69\">non-amortised: residual value greater than book value</span>Information systems<span class=\"_ _2fa\"> </span><span class=\"ff69\">20-33</span>Other intangible fixed assets<span class=\"_ _186\"> </span><span class=\"ff69\">20 or based on the duration of the contract</span>5.4 <span class=\"_ _82\"> </span>Public and private grantsCapital grants given by public authorities are recognised when there is reasonable certainty that the conditions imposed by the granting government agencies for their allocation will be met, and they are recognised as a reduction to the purchase or production cost of their related assets. Similarly, capital grants received from private entities are recognised in accordance with the same regulatory provisions.Operating grants are recognised in the income statement on an accruals basis, consistent with the relative costs incurred.5.5<span class=\"_ _0\"></span> <span class=\"_ _82\"> </span>Impairment of non-financial assets  Impairment of tangible and intangible assets with finite useful lifeAt least once a year<span class=\"_ _0\"></span>, non-financial, tangible and intangible assets with a finite useful life are analysed to uncover any indicators of impairment. When there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of property, plant and equipment or intangible assets with a finite useful life, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs(see paragraph 5.8 \u201cMeasurement at fair value\u201d), or the value in use, whichever is greater<span class=\"_ _3\"></span>.The recoverable amount, in the value in use configuration, is determined by discounting projected cash flows resulting from the use of the asset and, if they are significant and can be reasonably determined, from its sale at the end of its useful life, net of any disposal costs.With reference to the T<span class=\"_ _0\"></span>ransportation (Snam Rete Gas), Regasification (LNG) and Storage (Stogit) C<span class=\"_ _0\"></span>GUs, the recoverable value was defined as corresponding to the estimated value of the Net Invested Capital recognised to these assets for tariff 5purposes (R<span class=\"_ _4\"></span>AB - Regulatory Asset Base) by the Regulatory Authority for Energy, Networks and the Environment (ARER<span class=\"_ _4\"></span>A), net of the flat<span class=\"_ _0\"></span>-rate components, of the Employee Severance Indemnity (TFR) and of the contributions received.The measurement is made on a per-asset basis or for the smallest identifiable set of assets that, through its own continuous use, generates cash inflows that are largely independent of those of other assets or groups of assets (Cash Generating Units - CGUs). Expected cash flows are determined on the basis of reasonable and documentable assumptions representative of the best estimate of the future economic conditions of the asset or groups of assets, giving greater importance to indications from the outside. Discounting is done at a rate reflecting current market conditions for the time value of money and specific risks of the asset not reflected in the estimated cash flows. If the book value of the asset or CGU is greater than its recoverable amount, an impairment loss is recognised in the income statement; a CGU\u2019s impairment losses are first recognised as a reduction in the book value of any goodwill (see next point \u201cImpairment of goodwill and intangible assets not yet available for use\u201d) allocated to it and then as a reduction in the book value of the other assets of the CGU, in proportion to their respective carrying amounts. The book value of each Cash Generating Unit (or grouping of CGUs), consistently with the prevailing valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test<span class=\"_ _4\"></span>.If the conditions for a previously effected impairment no longer apply, the book value of the asset (except for goodwill) is restored with recognition in the income statement (recovery of value), within the limits of the net book value that the asset in question would have had if the impairment had not been carried out and any related amortisation had been carried out.    If certain specific assets held by the Group are affected by unfavourable operating or economic conditions that may compromise their ability to contribute to the realisation of cash flows, they may be subject to an independent recoverability analysis and impaired, if necessary. Impairment of goodwill,  intangible assets with an indefinite useful life and intangible assets not yet available for use.The recoverability of the book value of goodwill, of intangible assets with an indefinite useful life and intangible assets not yet available for use is tested at least annually, and in any case when events occur leading to an assumption of<span class=\"_ _0\"></span> impairment.Pursuant to the provisions of IFRS 3, in the context of business combinations, the acquirer<span class=\"_ _0\"></span>, at the acquisition date, recognises all assets, liabilities and identifiable contingent liabilities under the acquisition at their fair values; any remaining positive difference with respect to the acquisition cost is recognized in the asset item Goodwill, and any negative difference is recognised in the income statement.5 <span class=\"_ _48\"> </span>The RAB is the reference basis for the determination of the ser<span class=\"_ _4\"></span>vice tariffs and, therefore, of the cash flows generated by the activities. The value of the RAB is defined through the historical cost method revalued as regards the Fixed capital, and on a flat rate basis for the working capital, the employee severance indemnity and, with reference to the storage segment, the provision for decommissioning and site restoration.For the purpose of the impairment test, goodwill is allocated, as from the date of acquisition, to each Cash Generating Unit, or group of CGUs, that is expected to benefit from the synergies of the combination. After its initial recognition, goodwill is not amortised but is instead subject to a recoverability test at least annually by determining the recoverable value of the CGU or group of CGUs to which it is allocated (following the procedures described in the note \u201cImpairment of tangible and intangible assets of finite useful life\u201d); this is then compared to the book value of the CGU itself (or group of CGUs). The book value of each Cash Generating Unit<span class=\"_ _0\"></span> (or grouping of CGUs), consistently with the prevailing<span class=\"_ _0\"></span> valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test.When the book value of the CGU (or group of CGUs<span class=\"_ _0\"></span>), including the goodwill attributed to it, exceeds the recoverable value, the difference is subject to impairment, which is attributed by priority to the goodwill up to its amount; any surplus in the impairment with respect to the goodwill is attributed pro rata to the book value of the assets constituting the CGU (or group of CGUs<span class=\"_ _0\"></span>). Goodwill write-downs are not reversed, even if the reasons for the write- down no longer apply in subsequent years.<span class=\"ls0\"> </span>Reduction in value of Equity investmentsWhen there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of investments, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs (see paragraph 5.8 \u201cMeasurement at fair value\u201d), and the value in use, determined through the application of the 6Dividend Discount Model (DDM) or Discounted Cash Flow(DCF) method, (the present value of the expected cash flows is determined in accordance with the provisions of the previous paragraph \u201cImpairment of tangible and intangible assets with a finite useful life\u201d). The application of the Dividend Discount Model (DDM) provides that the recoverable value, in the configuration of the value in use, is determined by discounting the expected dividend flows on the basis of the forecast plans of the investee companies drawn up according to reasonable and documentable assumptions, discounted at the cost of the capital (Ke) which includes an<span class=\"_ _0\"></span>y specific risks not reflected in the estimated cash flows.6 <span class=\"_ _48\"> </span>If the Discounted Cash Flow (DCF) method is used, the results are adjusted for the respective net financial positions.5.6 InventoriesInventories, including compulsory inventories, are recorded at the lower of purchase or production cost and net realizable value, which is the amount that the entity expects to receive from their sale in the normal course of business, net of the estimated costs for the completion and the realisation of the sale.The cost of natural gas inventories is determined using the weighted average cost method.It should be noted that any transactions involving strategic gas, which are subject to prior authorisation by the MED, entail a withdrawal and subsequent replenishment of the quantities of gas from the strategic reserve, not resulting in 7any movement of the stock.  5.7 <span class=\"_ _82\"> </span>Financial instrumentsFinancial instruments are defined as any contract that gives rise to a financial asset, financial liability or equity instrument, which are recognized and measured in accordance with IAS 32 \"Financial Instruments: Presentation\" and IFRS 9 \"Financial Instruments.\" Financial instruments include, cash and cash equivalents, short<span class=\"_ _0\"></span>-term and long-term financial receivables and payables, trade receivables and payables, bonds held and issued, equity investments that do not constitute control, associates or joint control (so-called minority interests) and derivative instruments.Cash and cash equivalentsCash and cash equivalents include cash amounts, on demand deposits, and other short<span class=\"_ _0\"></span>-term financial assets with a term of less than three months, which are readily convertible into cash and for which the risk of a change in value is negligible. They are recorded at nominal value, corresponding to fair value.Financial assets - Initial recognitionA financial asset (or financial liability) is recognized in the financial statements when, and only when, the Group becomes a party to the contractual terms of the instrument (i.e., at the trade date).Initial recognition is at fair value, increased, for financial assets other than those measured at fair value with the effects charged to the income statement, by directly attributable transaction costs. For trade receivables without a significant financial component, the initial recognition value of which is the transaction price (as defined by IFRS 15).7 <span class=\"_ _48\"> </span>Or the risk, the timing or the amount of the future cash flows of the entity are not intended to change following these transactions (IFRS 15.9d)At initial recognition, financial assets are classified into the following categories: (i) financial assets measured at amortized cost; (ii) financial assets measured at fair value with the effects charged to other comprehensive income (hereinafter also FV<span class=\"_ _4\"></span>TOCI); and (iii) financial assets measured at fair value with the effects charged to the income statement, because of:\u2022 <span class=\"_ _29\"> </span>the business model identified for the management of financial assets (so-called \u201cBusiness Model\u201d);\u2022 <span class=\"_ _29\"> </span>the characteristics relating to the contractual cash flows of the financial asset, i.e., whether the cash flows generated by the financial asset consist solely of principal payments and accrued interest on the amount of principal to be repaid.  The Business Model for financial asset management determines whether cash flows will come from (i) the collection of cash under the contract, (ii) the sale of financial assets, or (iii) both.The test, aimed at determining whether the instrument generates cash flows representing solely payments of principal and interest (so-called \"Solely Payments of Principal and Interest\") and is referred to as the \"SPPI test\" and is performed at the individual instrument level.Financial assets \u2013 Subsequent measurementFinancial assets measured at amortised costFinancial assets at amortized cost mainly include trade receivables, other receivables, and financial receivables. Financial assets at amortized cost are held as part of a business model whose objective is to collect cash flows in accordance with contractual terms, represented exclusively by principal and interest on principal to be repaid at specific dates (so-called Hold T<span class=\"_ _0\"></span>o Collect business model).These assets, as indicated, are initially recognized at fair 8value, adjusted for transaction costs where appropriate, and subsequently measured at amortized cost using the effective interest rate.According to the amortised cost method the initial book value is then adjusted to account for repayments of principal, any impairments for credit losses and the amortisation of the difference between the repayment amount and the initial book value.Amortisation is carried out using the effective internal interest rate, which represents the rate that would make the present value of projected cash flows and the initial recognition value equal at the time of the initial recording.Financial assets valued at the amortised cost are presented in the statement of financial position net of the related 8 <span class=\"_ _48\"> </span>Except for trade receivables where, if they lack a significant financial component, they are initially recognized at transaction price (as defined in IFRS 15).provision for impairment losses.T<span class=\"_ _0\"></span>ransferred financial assets are derecognised from the balance sheet assets when the contractual rights to obtain the cash flows associated with the financial instrument expire, or all risks and rewards associated with the transferred receivable are transferred to a third party in accordance with the guidance on derecognition of financial assets set forth in IFRS 9.For financial assets measured at amortized cost, interest income determined on the basis of the effective interest rate, foreign exchange differences, and write-downs (including gains and losses from derecognition or modification of the asset) are recognized in the income statement.With specific reference to trade receivables, in order to measure Expected Credit Losses (\"ECLs\"), a valuation is made using the so-called \"simplified approach\" provided by IFRS 9, or - by virtue of the absence of a significant financial component - by estimating expected losses over the life of the receivable (\"lifetime ECLs<span class=\"_ _0\"></span>\").The assessment of the recoverability of trade receivables is made on both an individual and collective basis depending on the type of counterparty and whether there is reasonable and demonstrable information available to make an assessment at the individual instrument level.The group applies a specific definition of default, determined<span class=\"_ _4\"></span> by taking into account the characteristics of the operating segments to which the subsidiaries belong as well as the riskiness of the receivables and customers being assessed. Therefore, beyond the time limit of default, trade receivables<span class=\"_ _4\"></span> are assumed to be impaired (i.e. credit<span class=\"_ _0\"></span>-impaired).In particular<span class=\"_ _0\"></span>, expected losses are generally determined on the basis of the product between: (i) <span class=\"_ _16\"> </span>the amount of exposure to the counterparty at the time of default (so-called 'Exposure At Default' or 'EAD');(<span class=\"_ _4\"></span>ii<span class=\"_ _4\"></span>)<span class=\"_ _4\"></span> <span class=\"_ _8\"> </span>the probability that the counterparty will default on its<span class=\"_ _4\"></span> payment obligations (so-called Probability of Default or PD); (iii) the estimate, in percentage terms, of the amount of credit that will not be recovered in the event of default (so-called Loss Given Default or L<span class=\"_ _0\"></span>GD).With regard to the ECL parameters listed above, the group considers the following assumptions:(i) <span class=\"_ _16\"> </span>PD is determined according to the type of counterparty on the basis of:\u2022 <span class=\"_ _29\"> </span>qualified external providers (e.g. for listed companies);\u2022 <span class=\"_ _29\"> </span>regional ratings (e.g. for public administration<span class=\"_ _0\"></span>) by leading rating agencies;\u2022 <span class=\"_ _29\"> </span>average default rate calculated for groups of customers broken down by common credit risk (so-called 'cluster') considering historical data over a period of at least 24 months; (ii) <span class=\"_\"> </span>the LGD is obtained on the basis of market standards that assess the recovery rate of the exposure depending on the region and sector of the counterparty (e.g. corporate, government and retail);(iii) the E<span class=\"_ _4\"></span>AD is determined to be equal to the face value of the claim at the valuation date, less any related mitigating factor<span class=\"_ _0\"></span>, including any amounts pledged as collateral.In the case of credit exposures in litigation and where detailed information is available on the recoverability of the exposure, analytical assessments are performed in order to better reflect the actual riskiness of the position in the determination of expected losses. The exposures for which credit recovery actions have been activated through legal/court proceedings are defined as litigation.Impairments of trade receivables and other receivables are recognised in the income statement, net of any write-backs, under the item \u201cOther operating expenses\u201d.Financial assets, measured at fair value with effects recognized in other comprehensive income (FVTOCI) Credits and Debt Instrument<span class=\"_ _4\"></span>sIf present, financial assets representing loans and debt instruments whose business model envisages the possibility of both collecting the contractual cash flows and realizing their value through sale (so-called Hold to Collect and Sell, or Mixed, Business Model) are measured at fair value with the effects charged to OCI (so-called FV<span class=\"_ _4\"></span>TOCI). Under this measurement criterion, interest income, calculated using the effective interest rate, exchange rate differences and impairment losses are recognized in the income statement; changes in the fair value of the instrument are recognized in equity, among other components of comprehensive income.When a financial asset is derecognized (e.g., upon sale), the cumulative amount of changes in fair value, up to that point recognized in OCI, are reclassified to the income statement.The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\" - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Financial assets measured at fair value with effects charged to the income statementCredits and Debt Instrument<span class=\"_ _4\"></span>sThe category of financial assets measured at fair value through profit or loss (so-called FV<span class=\"_ _4\"></span>TPL) includes:\u2022 <span class=\"_ _29\"> </span>financial assets with cash flows that are not represented exclusively by principal and interest payments, regardless of the business model (financial assets that do not pass the SPPI test);\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets held for trading because they are </span>purchased or held primarily for the purpose of being sold (financial assets that pass SPPI test but held under a so-called Business Model T<span class=\"_ _0\"></span>rading)\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets for which the entity voluntarily adopts </span>the so-called Conditional F<span class=\"_ _0\"></span>air Value Option (these are<span class=\"_ _0\"></span> financial assets that pass the SPPI T<span class=\"_ _0\"></span>est and for which despite the Business Model being Hold to Collect or Mixed, the company decides to exercise the option<span class=\"_ _0\"></span> granted by IFRS 9 that allows the financial asset to be valued at FV<span class=\"_ _4\"></span>TPL).Where present, credits arising from invoice rebates to customers in the energy efficiency business (pertaining to so-called \"Ecobonus\" and \"Superbonus\") - and which<span class=\"_ _0\"></span> are converted into tax credits - if held with the objective of realizing cash flows through sale (so-called \"Other\" Business Model) are measured at fair value with the effects charged to the income statement (so-called FV<span class=\"_ _4\"></span>TPL).The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\"<span class=\"_ _0\"></span> - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Minority interestFinancial assets representing minority interests, which are not held for trading purposes, are measured at fair value alternatively with recognition of the effects: (i) in the income statement (so-called fair value measurement recognized in the income statement or FV<span class=\"_ _4\"></span>TPL) or in the equity reserve that holds the other components of comprehensive income, without provision for their reclassification to the income statement in the event of realization (so-called fair value measurement recognized in the statement of comprehensive income or FV<span class=\"_ _4\"></span>TOCI).This classification can be made on a security-by-security basis, only upon initial recognition, and is irrevocable.Dividends from such equity investments are recognized in the income statement under \"Income (expense) on equity investments,\" unless the dividend clearly represents a recovery of part of the cost of the investment; in which case the dividend is recognized as a direct reduction of the carrying amount of the equity investment<span class=\"_ _4\"></span>. Valuation<span class=\"_ _0\"></span> at cost of a minority investment is permitted in the limited cases where cost represents an adequate estimate of fair value.The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\"<span class=\"_ _0\"></span> - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Financial liabilitiesFinancial liabilities, unlike derivative instruments, including financial debt, trade payables and other payables, are initially recorded at fair value less any transaction- related costs; they are subsequently recognised at amortised cost using the effective interest rate for discounting purposes, as demonstrated in the previous point \"Financial assets valued at amortized cost\u201d.Financial liabilities are derecognized upon extinguishment or upon fulfilment, cancellation or maturity of the contractual obligation. Offsetting a financial asset and a financial liabilityFinancial assets and liabilities are offset in the statement of financial position when there is a currently legally enforceable right to set<span class=\"_ _0\"></span>-off and the intention either to settle the relationship on a net basis (i.e. to realise the asset and settle the liability simultaneously). Derivative financial instruments and hedge accountingDerivative financial instruments, including embedded derivatives, are assets and liabilities recognised at fair value. Under the scope of the strategy and objectives defined for risk management, the qualification of transactions as hedging requires: (i) the verification of the existence of an economic relationship between the object hedged and the hedging instrument for the purpose of offsetting the changes in value and ensuring this offsetting capacity is not invalidated by the level of counterparty credit risk; (ii) the definition of a hedge ratio consistent with the risk management objectives, under the scope of the risk management strategy defined, where necessary activating the appropriate rebalancing actions. The amendments of the risk management objectives, the disappearance of the conditions indicated previously for the qualification of transactions as hedging or the activation of rebalancing operations cause the total or partial prospective discontinuation of the hedge.In order to qualify a transaction as a hedge, at the start of the hedge a formal document is prepared that illustrates the strategies and objectives of the risk management and identifies the hedging instrument, the instrument hedged, the nature of the risk hedged and the methods through which the evaluation of whether the hedge relationship satisfies the hedge effectiveness requirements takes place.When hedging derivatives hedge the risk of changes in the fair value of the hedged instruments (\u201cfair value hedge\u201d; e.g. hedge of the risk of fluctuations in the fair value of fixed-rate assets/liabilities), the derivatives are recognised<span class=\"_ _0\"></span> at fair value with attribution of the effects on the income statement; by the same token, the hedged instruments are adjusted to reflect in the income statement the changes in fair value associated with the hedged risk, regardless of the provision of a different valuation criterion generally applicable to the instrument type.The group subscribes to derivative instruments to cover the risk of changes in cash flows (cash flow hedges) as a result of fluctuations in interest rate or exchange rates. Changes in the fair value of hedging derivatives considered effective are initially recognised in the shareholders\u2019 equity reserve relating to other components in the comprehensive income statement and are subsequently reclassified to profit or loss in line with the economic effects produced by the hedged transaction. In the case of hedging future transactions that involve the recording of a non-financial asset or liability, the cumulative variations of the fair value of the hedge derivatives, recognised in shareholders\u2019 equity, are recognised in the adjustment of the book value of the non- financial asset/liability subject to hedging (basis adjustment).The ineffective portion of the hedge and the changes in the fair value of derivatives that do not meet the qualifying conditions for hedging are recognised in the income statement.<span class=\"ls0\"> </span>T<span class=\"_ _3\"></span>reasury sharesT<span class=\"_ _0\"></span>reasury shares, including those held to ser<span class=\"_ _4\"></span>vice share-based payment plans (share incentive plans), are measured at cost and entered as a reduction of shareholders\u2019 equity. The economic effects arising from any subsequent sales are recognised in shareholders\u2019 equity.Distribution of dividendsThe distribution of dividends to the Company\u2019s shareholders entails the recording of a payable in the financial statements for the period in which distribution was approved by the Company\u2019s shareholders or<span class=\"_ _0\"></span>, in the case of interim dividends, by the Board of Directors.5.8 <span class=\"_ _82\"> </span>Fair value measurementThe fair value is the amount that may be received for the sale of an asset or that may be paid for the transfer of a liability in a regular transaction between market<span class=\"_ _0\"></span> operators as at the valuation date (i.e. exit price).The fair value of an asset or liability is determined by adopting the valuations that market operators would<span class=\"_ _0\"></span> use to determine the price of the asset or liability. A<span class=\"_ _0\"></span> fair value measurement also assumes that the asset or liability would be traded on the main market or<span class=\"_ _3\"></span>, failing that, on the most advantageous market to which the Company has access.The fair value of a non-financial asset is determined by considering the capacity of market operators to<span class=\"_ _0\"></span> generate economic benefits by putting the asset to its maximum and best use or by selling it to another market participant capable of using it in such a way as<span class=\"_ _0\"></span> to maximise its value. The maximum and best use of an asset is determined from the perspective of market<span class=\"_ _0\"></span> operators, also hypothesising that the company intends<span class=\"_ _0\"></span> to put it to a different use; the current use by the company of a non-financial asset is assumed to be the maximum and best use of this asset, unless the market or other factors suggest that a different use by market<span class=\"_ _0\"></span> operators would maximise its value.The fair-value measurement of a financial or non-financial liability, or of an equity instrument, takes<span class=\"_ _0\"></span> into account the quoted price for the transfer of an identical or similar liability or equity instrument; if this quoted price is not available, the valuation of a corresponding asset held by a market operator as at<span class=\"_ _0\"></span> the valuation date is taken into account. The fair value of financial instruments considers the credit risk of the counterparty for financial assets (through a \u201cCredit<span class=\"_ _0\"></span> Valuation Adjustment\u201d - CV<span class=\"_ _0\"></span>A) and the entity\u2019s own risk of default for financial liabilities (through a \u201cDebit Valuation<span class=\"_ _0\"></span> Adjustment\u201d - DV<span class=\"_ _3\"></span>A).When determining fair value, a hierarchy is set out<span class=\"_ _0\"></span> consisting of criteria based on the origin, type and quality of the information used in the calculation. This classification aims to establish a hierarchy in terms of the<span class=\"_ _0\"></span> reliability of the fair value, giving precedence to the use of parameters that can be observed on the market and that reflect the assumptions that market participants<span class=\"_ _0\"></span> would use when valuing the asset/liability.<span class=\"_ _0\"></span> The fair value hierarchy includes the following levels:\u2022 <span class=\"_ _29\"> </span>level 1: listed prices (unadjusted) in active mark<span class=\"_ _0\"></span>ets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;\u2022 <span class=\"_ _29\"> </span>level 2: inputs, other than the quoted prices included in Level 1, that can be directly or indirectly observed for the assets or liabilities to be valued;\u2022 <span class=\"_ _29\"> </span>level 3: inputs for assets or liabilities that are not based on observable market data.In the absence of available market quotations, the fair value is determined by using valuation techniques suitable for each individual case that maximise the use of significant observable inputs, whilst minimising the use of non-observable inputs.5.9 <span class=\"_ _82\"> </span>Provision for risks and charges,  <span class=\"_ _70\"> </span>contingent liabilities and contingent assetsProvisions for risks and charges concern costs and charges of a certain nature which are certain or likely to be incurred, but for which the amount or date of occurrence cannot be determined at the end of the year<span class=\"_ _0\"></span>.The provisions are recognised when: (i) the existence of a current legal or implied obligation arising from a past event is probable; (ii) it is probable that the fulfilment of the obligation will involve a cost; and (iii) the amount of the obligation can be reliably determined. Provisions are recorded at the value representing the best estimate of the amount that the Company would reasonably pay to fulfil the obligation or to transfer it to third parties at the end of the reporting period.Provisions related to contracts with valuable consideration are recorded at the lower of the cost necessary to fulfil the obligation, less the expected economic benefits arising from the contract, and the cost of terminating the contract.When the financial impact of time is significant, and the payment dates of the obligations can be reliably estimated, the provision is calculated by discounting the anticipated cash flows in consideration of the risks associated with the obligation at the Company\u2019s average debt rate; the increase in the provision due to the passing of time is posted to the income statement under \u201cFinancial income (expense)\u201d.When the liability is related to items of property, plant and equipment (e.g. decommissioning and site restoration), the provision is recognised as a counter-entry to the related asset, and posting to the income statement is accomplished through amortisation. The costs that the Company expects to incur to initiate restructuring programmes are recorded in the period in which the programme is formally defined, and the parties concerned have a valid expectation that the restructuring will take place.Provisions are periodically updated to reflect changes in cost estimates, selling periods and the discount rate; revisions in provision estimates are allocated to the same item of the income statement where the provision was previously reported or<span class=\"_ _0\"></span>, when the liability is related to property, plant and equipment (e.g. site dismantling and restoration), as a contra-entry to the related asset, up to the book value; any surplus is posted to the income statement.The notes to the financial statements describe contingent liabilities represented by: (i) possible (but not probable) obligations resulting from past events, the existence of which will be confirmed only if one or more future uncertain events occur which are partially or fully outside the Company\u2019s control; and (ii) current obligations resulting from past events, the amount of which cannot be reliably estimated, or the fulfilment of which is not likely to involve costs.Contingent assets, or possible assets that result from past events and whose existence will only be confirmed when one or more uncertain future events, not totally under the control of the business, occur or do not occur<span class=\"_ _0\"></span>, are not recognised unless obtaining the related benefits is virtually certain. If obtaining the benefits is probable, the contingent assets are illustrated in the notes to the financial statements.5.10 <span class=\"_ _34\"> </span>Non-current assets held for sale  and discontinued operationsNon-current assets or disposal groups consisting of assets and liabilities are classified as held for sale if their book value will be recovered mainly by their sale rather than through continued use. This condition is regarded as fulfilled when the sale is highly probable and the asset or discontinued operations are available for immediate sale in their current condition. In the case of a programme for the sale of a subsidiary that results in loss of control, all assets and liabilities of that subsidiary are classified as held for sale, regardless of whether a non-controlling investment is maintained following the sale. V<span class=\"_ _0\"></span>erification of compliance with the terms and conditions provided for classification of an item as held for sale requires management to make subjective valuations formulating reasonable and realistic assumptions based on the information available to it. Immediately prior to classification as held for sale, the assets and liabilities included in a disposal group are measured in accordance with the accounting standards applicable to them. Subsequently, non- current assets held for sale are not amortised or depreciated and are measured at the lower of book value and related fair value, less any sales costs (see paragraph 5.8 \u201cF<span class=\"_ _0\"></span>air<span class=\"_ _0\"></span>-value measurements\u201d above).The classification of investments accounted for using the equity method as held for sale implies the suspension of the application of this valuation criterion. Any negative difference between the book value of the non-current assets and their fair value less selling costs is posted to the income statement as an impairment loss; any subsequent recoveries in value are recognised up to the amount of the previously recognised impairment losses, including those recognised prior to the asset being classified as held for sale.Non-current assets and disposal group- related assets and liabilities held for sale are recognised in the statement of financial position separately from the group\u2019s other assets and liabilities.Non-current assets and disposal groups, classified as held for sale, constitute a discontinued operation if<span class=\"_ _0\"></span>, alternatively:  (i) <span class=\"_ _16\"> </span>they represent a significant autonomous business unit or a significant geographical area of operations; (ii) <span class=\"_\"> </span>they are part of a plan to dispose of a significant autonomous business unit or a significant geographical area of operations;  (iii) they relate to a subsidiar<span class=\"_ _4\"></span>y acquired exclusively to be sold. The economic results of discontinued operations, as well as any capital gains/losses realised on the disposal, are recorded separately in the Income Statement under a special item, net of related tax effects, including for the comparative periods.When events occur that no longer permit non-current assets or disposal groups to be classified as held for sale, they are reclassified to the respective items in the statement of financial position and recognised at the lower of the following: (i) the book value at the date of classification as held for sale; and (ii) the recoverable amount at the reclassification date.5.1<span class=\"_ _3\"></span>1 RevenueThe recognition of revenue from contracts with customers is based on the following five steps: (i) identification of the contract with the customer; (ii) identification of the performance obligation, represented by the contractual commitment to transfer goods and/or services to a customer; (iii) calculating of the transaction\u2019s price; (iv) allocating of the transaction price to the performance obligations identified based on the stand alone sales price of each of the goods or services; (v) measuring the revenue when the performance obligation is met, i.e. at the time of the transfer to the customer of the goods or services promised; the transfer is considered to be completed when the customer obtains control of the goods or service, which can take place over time or at a point in time.Revenues are measured for the amount equal to the fair value of the consideration which the business believes it has the right to in exchange for the goods and/or services promised to the customer<span class=\"_ _0\"></span>, with the exception of amounts collected on behalf of third-parties. If there is a variable consideration, the business estimates the amount of the consideration it shall have the right to in exchange for the transfer of goods and/or services promised to the customer;<span class=\"_ _4\"></span> specifically, the amount of the consideration can vary in the presence of discounts, incentives, concessions on the price, performance bonuses, penalties or if the actual price depends on certain future events taking place or not.Revenues from the Snam Group\u2019s ordinary operations mainly consist of services relating to the transportation, dispatching and storage of natural gas and the regasification of liquefied natural gas, which are recognised in the financial statements over the period in which the service is provided, whether the ser<span class=\"_ _4\"></span>vices are \u201cregulated\u201d or \u201cnon-regulated\u201d. The recognition of revenues for regulated services is conditioned and influenced by the regulatory framework defined by ARER<span class=\"_ _4\"></span>A (Autorit\u00e0 di Regolazione per Energia Reti e Ambiente \u2013 Regulatory Authority for Energy Networks and the Environment). Therefore, the economic conditions of the services provided are defined through regulator<span class=\"_ _4\"></span>y schemes and not on a negotiated basis. The revenue recognised in the income statement coincides with that recognised by the regulator (so-called \u201crevenue cap\u201d). As regards the transportation business segment, the difference between the revenue recognised by the regulator (so- called \u201crevenue cap\u201d) and that actually accrued is recorded, if positive, in the item of the statement of financial position \u201cTrade payables and other payables\u201d and, in the item \u201cTrade and other payables\u201d, as it will be subject to cash settlement with the Cassa per i Servizi Energetici e Ambientali (CSEA). In the Regasification and Storage segments any difference between the revenue recognised by the regulator and the accrued revenue is recognised in the balance sheet item \u201cTrade and other receivables\u201d, if positive, and in the item \u201cTrade payables and other payables\u201d, if negative, inasmuch as it will be subject to cash settlement with the Energy and Environmental Services Fund (CSEA).Non-regulated revenues mainly involve: (i) considerations for the construction of biogas and biomethane plants; (ii) technical- specialist services to unconsolidated foreign companies; (iii) the provision of services relating to energy efficiency projects; (iv) income from the rental and maintenance of fibre optic telecommunication cables; (v) the sale of CNG compressors for motor transport. The recognition of these revenues takes place over the service provision period.By virtue of the principle of neutrality defined by applicable regulations, transactions carried out on the balancing market generate neither costs nor revenue, as they are mere pass-through items. Any (positive or negative) differences from the usage of different prices for the transactions above will be neutralized by recognizing an asset or liability for CSEA<span class=\"_ _4\"></span>, given that these differences are equalized by the latter<span class=\"_ _0\"></span>. 5.12 <span class=\"_ _34\"> </span>Employee benefitsShort-term benefits for employeesShort<span class=\"_ _0\"></span>-term benefits for employee are recognised as a cost at the time when the service is rendered. The Group recognises a liability, classified under \u201cTrade payables and<span class=\"_ _0\"></span> other payables\u201d for the amount due to be paid when it has a current legal or constructive obligation to make such payments.<span class=\"ls0 ws0\"> </span>Post-employment benefitsPost<span class=\"_ _0\"></span>-employment benefits are defined according to programmes, including non- formalised programmes, which, depending on their characteristics, are classed as \u201cdefined-benefit\u201d or \u201cdefined-contribution\u201d plans.\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\"> Defined-benefit plansi</span>The liability associated with defined-benefit plans is determined by estimating the present value of the future benefits accrued by the employees during the current year and in previous years, and by calculating the fair value of any assets servicing the plan. The present value of the obligations is determined based on actuarial assumptions and is recognised on an accruals basis consistent with the employment period necessary to obtain the benefits.Actuarial gains and losses relating to defined-benefit plans arising from changes in actuarial assumptions or experience adjustments are recognised in the comprehensive income statement in the period in which they occurred,and are not subsequently recognised in the income statement. When a plan changed, reduced or extinguished, the relative effects are recognised in the income statement.Net financial expense represents the change that the net liability undergoes during the year due to the passing of time. Net interest is determined by applying to the liabilities, net of any plan assets, the discount rate used for the discounting used for the liabilities. The net financial expense of defined-benefit plans is recognised in \u201cFinance expense (income)\u201d.\u2022 <span class=\"_ _33\"> </span><span class=\"ff63 ws0\">Defined-contribution plans</span>In defined-contribution plans, the Company\u2019s obligation is calculated, limited to the payment of state contributions or to equity or a legally separate entity (fund), based on contributions due. The costs associated with defined-benefit contributions are recognised in the income statement as and when they are incurred.Other long-term benefitsObligations relating to other long-term benefits are calculated using actuarial assumptions; the effects arising from the amendments to the actuarial assumptions or the characteristics of the benefits are recognised entirely in the income statement. Benefits payable on termination of employmentThe benefits payable to employees for termination of employment are recognised as an expense when the Company is committed to offering the benefits and has no option to withdraw them, or<span class=\"_ _0\"></span>, if earlier<span class=\"_ _3\"></span>, when the company recorded restructuring costs. Share-based payments (Share-based incentive plan)Employee benefits, consistent with the essential nature of the remuneration that they comprise, include the cost of share-based incentive plans. The incentive cost is calculated with reference to the fair value of the instruments allocated and the forecast of the number of share that will effectively be allocated; the share pertaining to the financial year is calculated pro-rata temporis throughout the vesting period, or the period between the grant date and the allocation date. The fair value of the shares underlying the incentive plan is calculated at the grant date taking into account the forecasts with regard to reaching the performance parameters associated with market conditions and is not adjusted in future financial years; when obtaining the benefit is also connected to conditions other than market conditions, the estimate relating to these conditions is reflected by adjusting the number of shares during the vesting period that are expected to effectively be allocated.5.13 <span class=\"_ _34\"> </span>Accounting for environmental  certificates - Emission trading  systemsThe European Emission T<span class=\"_ _0\"></span>rading System, established to manage and trade emission allowances, sets an upper limit for greenhouse gas emissions produced over the course of a year<span class=\"_ _0\"></span>, for which a certain number of emission allowances are issued free of charge by the competent national authorities. Depending on the actual greenhouse gas emissions produced during the year<span class=\"_ _0\"></span>, each company is entitled to sell or is obliged to buy emission allowances on the market.Allowances purchased for a consideration to offset emissions released into the atmosphere during the year are recognised in the income statement; any allowances purchased beyond what is necessary are recognised in \u201cOther current assets\u201d.Any allowances allocated free of charge and not used in the year of allocation are not recognised in the financial statements as they are used for the following year\u2019s requirements.If there is a deficit for emission allowances that have not been purchased on the market at the balance sheet date, the cost and corresponding liability are recognised at market value at the end of the financial year<span class=\"_ _3\"></span>.5.14 <span class=\"_ _34\"> </span>Foreign currency transactionsThe criteria adopted by Snam to convert transactions in currencies other than the functional currency (the Euro) are summarised below:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">revenue and costs relating to transactions in currencies </span>other than the functional currency are recognised at the exchange rate in effect on the day when the transaction was carried out;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">monetar<span class=\"_ _4\"></span>y assets and liabilities in currencies other than </span>the functional currency are converted into Euro by applying the exchange rate in effect on the reporting date, allocating the effect to the income statement;\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">non-monetar<span class=\"_ _4\"></span>y assets and liabilities in currencies other </span>than the functional currency which are valued at cost are recognised at the initially recorded exchange rate; when the measurement is made at fair value or recoverable or realisable value, the exchange rate used is the one in effect on the valuation date.5.15 <span class=\"_ _34\"> </span>Income taxesCurrent income taxes are calculated by estimating<span class=\"_ _0\"></span> the taxable income. T<span class=\"_ _0\"></span>ax payables and receivables for current taxes are recognised at the value of the current tax liability that are expected to be paid/recovered to/from the tax authorities by applying the tax rates and regulations in force or substantially approved at the end of the financial year<span class=\"_ _0\"></span>. Regarding corporation tax (IRES), Snam has exercised the option to join the national tax consolidation scheme, to which all the consolidated companies have officially signed up, except for Mieci S.p.<span class=\"_ _4\"></span>A., Evolve S.p.<span class=\"_ _4\"></span>A<span class=\"_ _4\"></span>. and T<span class=\"_ _0\"></span>-lux S.r<span class=\"_ _0\"></span>.l. The projected payable is recognised under \u201cCurrent tax liabilities\u201d.The regulations governing Snam Group companies\u2019 participation in the national tax consolidation scheme stipulates that:\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">subsidiaries with positive taxable income pay the </span>amount due to Snam. The taxable income of the subsidiary, used to determine the tax, is adjusted to account for the recovery of negative components that would have been non-deductible without the consolidation scheme (e.g. interest expense), the so-called ACE (help for economic growth) effect and an<span class=\"_ _0\"></span>y negative taxable income relating to the subsidiary<span class=\"_ _4\"></span>\u2019s equity investments in consolidated companies;\u2022 <span class=\"_ _29\"> </span>subsidiaries with negative taxable income, if and insofar as they have prospective profitability which, without the national tax consolidation scheme, would have enabled them to recognise deferred tax assets related to the negative taxable income on the separate financial statements, receive from their shareholders \u2013 in the event that these are companies with a positive taxable income or a negative taxable income with prospective profitability \u2013 or from Snam in other cases, compensation amounting to the lower of the tax saving realised by the Group and the aforementioned deferred tax assets.Regional production tax (IR<span class=\"_ _4\"></span>AP<span class=\"_ _0\"></span>) is recognised under the item \u201cCurrent tax liabilities\u201d/\u201c<span class=\"_ _0\"></span>Current tax assets\u201d.Deferred taxes are calculated on the timing differences between the values of the assets and liabilities entered in the balance sheet and the corresponding values recognized for tax purposes, based on the prevailing tax regulations and rates applicable in financial years in which the temporary difference will be cancelled, approved or essentially approved at the end closing date of the reference year of the financial statements. Deferred tax assets are recognised when their recovery is considered probable; specifically, the recoverability of deferred tax assets is considered probable when taxable income is expected to be available in the period in which the temporary difference is cancelled, allowing the activation of the tax deduction. Similarly, unused tax credits and deferred tax assets on tax losses are recognised within the limits of their recoverability; with reference to deferred tax assets, their recoverability is verified at least annually.If there are uncertainties over the application of tax regulations: (i) in cases where it is deemed probable that the tax authorities will accept the uncertain tax treatment, the income taxes (current and/or deferred) to be recognised in the financial statements according to the tax treatment applied or which it is expected to apply during the tax return are calculated; (ii) in cases where it is not deemed probable that the tax authorities will accept the uncertain tax treatment, this uncertainty is reflected in calculating the (current and/or deferred) income taxes to be recognised in the financial statements.Deferred tax assets and deferred tax liabilities are classified under non-current assets and liabilities and are offset at individual company level if they refer to taxes which can be offset and/or at the level of the consolidating company in the presence of the taxation regime set out in the national consolidation scheme. The balance of the offsetting, if it results in an asset, is recognised under the item \u201cDeferred tax assets\u201d; if it results in a liability, it is recognised under the item \u201cDeferred tax liabilities\u201d. When the results of transactions are recognised directly in equity, current and deferred taxes are also posted to equity.5.16 <span class=\"_ _34\"> </span>Segment reporting  (operating segments)Disclosure on business segments has been prepared pursuant to IFRS 8 \u2013 \u201cOperating Segments\u201d:consequently, the identification of the operating segments and the information presented are defined on the basis of the internal reporting used by the Company\u2019s management to allocate resources to the different segments and to analyse the respective performances.An operating segment is defined by IFRS 8 as the component of<span class=\"_ _4\"></span> an entity that: (i) that engages in business activities from which<span class=\"_ _4\"></span> it may earn revenue and incur expenses (including revenue and<span class=\"_ _4\"></span> expenses relating to transactions with other components of the<span class=\"_ _4\"></span> same entity); (ii) for which the operating results are regularly<span class=\"_ _4\"></span> reviewed by the entity\u2019s most senior decision-makers for the purpose of making decisions about resources to be allocated to<span class=\"_ _4\"></span> the segment and assessing its performance; and (iii) for which<span class=\"_ _4\"></span> separate financial information is available.With reference to the financial year 2022, the business segments subject to reporting under IFRS 8 are: (i) the T<span class=\"_ _0\"></span>ransportation segment, relating to natural gas transportation<span class=\"_ _4\"></span> activities; (ii) the Regasification segment, relating to Liquefied<span class=\"_ _4\"></span> Natural Gas regasification activities; (iii) the Storage segment,<span class=\"_ _4\"></span> relating to natural gas storage activities; (iv) the Energy transition segment, relating to energy efficiency, biogas/biomethane business and hydrogen start<span class=\"_ _0\"></span>-up projects. The Mobility segment, together with the activities of Snam Global solution, do not constitute operating segments subject to separate reporting under IFRS 8. The relevant values are shown in the aggregate \"Other segments\". 6ASSUMPTIONS AND<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>UNCERT<span class=\"_ _32\"></span>AINTIES IN ESTIMA<span class=\"_ _3\"></span>TES  The application of generally accepted accounting principles for the preparation of financial statements involves management making accounting estimates based on complex and/or subjective judgements, estimates based on past experience and assumptions regarded as reasonable and realistic on the basis of the information known at the time of the estimate. The use of these accounting estimates has an influence on the book value of the assets and liabilities and on the information about potential assets and liabilities at the reporting date, as well as the amount of revenue and costs in the reference period. The actual results may differ from the estimated results owing to the uncertainty that characterises the assumptions and the conditions on which the estimates are based. Details are given below about the critical accounting estimates involved in the process of preparing the financial statements and interim reports, since they involve a high degree of recourse to subjective judgements, assumptions and estimates regarding matters that are by nature uncertain. Any change in the conditions forming the basis of the judgements, assumptions and estimates used could have a significant impact on subsequent results.6.1 <span class=\"_ _82\"> </span>Impairment of non-financial assetsNon-financial assets are impaired when events or changes in circumstances give cause to believe that the book value is not recoverable. The events that can lead to an impairment of assets include changes in business plans, changes in market prices or reduced use of plants. The decision on whether to apply an impairment and the quantification of any such impairment depend on the Company\u2019s management assessment of complex and highly uncertain factors, such as future price trends, the impact of inflation and technological improvements on production costs, production profiles and conditions of supply and demand. The impairment is determined by comparing the book value with the related recoverable value, represented by the greater of the fair value, net of disposal costs, and the usage value, determined by discounting the expected cash flows deriving from the use of the asset, or represented by the R<span class=\"_ _4\"></span>AB in the regulated business segments. The expected cash flows are quantified in the light of the information available at the time of the estimate, on the basis of subjective judgements regarding future trends in variables \u2013 such as prices, costs, the rate of growth of demand and production profiles \u2013 and are discounted using a rate that takes account of the risk inherent to the asset concerned. The rationale behind the impairment testing used by management in relation to property plant and machinery, intangible assets, goodwill and investments<span class=\"_ _4\"></span> accounted for using the equity method are illustrated respectively in note 8 \u201c\u2018Property, plant and equipment\u2019\u201d, note 9 \u201c\u2018Intangible assets and goodwill\u201d and note 10 \u201cInvestments accounted for using the equity method\u201d.6.2 <span class=\"_ _82\"> </span>Impairment of financial assetsAt each reporting date, assessments are made of the recoverability of financial assets in order to determine the value of expected credit losses (ECL).In particular<span class=\"_ _0\"></span>, the valuation of trade receivables is carried out using the simplified approach established by IFRS 9, which involves estimating the ECL over the life of the receivable. In these cases, the impairment is generally based on the expected credit loss model and is carried out through the use of both qualified external providers and by means of an analysis of observed historical data with respect to credit recoverability; analysis performed for homogeneous categories of counterparties. On the other hand, for certain categories of credits characterised by peculiar risk elements (e.g. litigation or credit recovery practices through legal/judicial proceedings), specific assessments are carried out on individual credit positions. The logic behind the expected credit loss model is explained in Note 5 \"Significant accounting standards\" - \"Non-derivative Financial Assets -Receivables and Debt securities\", respectively.6.3 <span class=\"_ _82\"> </span>Provisions for risks and charges  Provision for decommissioning and site restorationThe Snam Group incurs significant liabilities associated with obligations to remove and dismantle plants or parts of plants. Estimating future dismantling and restoration costs is a complex process and requires the assessment and judgement of the Company\u2019s management in placing a value on the liabilities that will be incurred many years in the future for compliance with dismantling and restoration obligations, which often cannot be fully defined by laws, administrative regulations or contractual clauses. In addition, these obligations are affected by constant changes in technology and in dismantling and restoration costs, as well as the constant growth of political and public awareness regarding matters of health and protection of the environment.The criticality of estimates of dismantlement and restoration costs also depends on the accounting method used for these costs, for which the current value is initially capitalised together with the cost of the asset to which they relate, offset against the provision for risks and charges. Thereafter<span class=\"_ _0\"></span>, the value of the provision for risks is updated to reflect the passing of time and any changes in the estimate as a result of changes in expected cash flows, the timing of their realisation and the discount rates applied.The calculation of the discount rate to be used both in the initial valuation of the cost and in subsequent valuations is the result of a complex process which involves subjective judgements on the part of the Company\u2019s management. Environmental liabilitiesThe Snam Group is subject, in relation to its activities, to numerous laws and regulations on environmental protection at European, national, regional and local level, including the laws which implement international conventions and protocols relating to the activities carried out. With reference to this legislation, when it is probable that the existence and amount of a large liability can be reliably estimated, provisions are made for the associated costs.The group does not currently believe that the financial statements will suffer particularly significant adverse effects due to non-compliance with environmental regulations, also considering actions already undertaken, but it cannot be ruled out with certainty that Snam may incur further<span class=\"_ _0\"></span>, possibly significant, costs or liabilities, since current knowledge says it is impossible to predict the effects of future developments, taking into account also the following aspects: (i) the possible emergence of contamination; (ii) the outcome of the refurbishment in progress and to be followed and the other possible effects arising from the application of the laws in force; (iii) the possible effects of new laws and regulations for environmental protection; (iv) the effects of any technological innovations for environmental reclamation; (v) the possibility of disputes and the difficulty of determining the possible consequences, also in relation to the liability of other parties and to possible compensation payments.Provisions for legal and tax disputesThe estimation of the group\u2019s provisions for these purposes is the result of a complex process involving subjective judgements by Company management.6.4 <span class=\"_ _82\"> </span>Investments and business  combinationsV<span class=\"_ _0\"></span>erification of the existence of control, joint control, considerable influence over another entity as well as, in the case of joint operations, verification of the existence of enforceable rights and obligations requires Corporate Management to exercise professional judgement taking into consideration the characteristics of the corporate structure and agreements between the parties as well as other facts and circumstances that are relevant for the purpose of this check. Similar considerations also apply in cases of a planned change in status following a loss of control, joint control or connection with the possible need to activate the classification as \u201cassets held for sale/discontinued operation\u201d.The reporting of business combination transactions involves the allocation to the assets and liabilities of the acquired company of the difference between the acquisition cost and the net book value. For the majority of assets and liabilities, the attribution of the difference is carried out by recognising the assets and liabilities at their fair value. The unallocated portion, if positive, is recognised as goodwill; if negative, it is allocated to the income statement. In the allocation process, the Snam Group draws on the available information and, for the most significant business combinations, on external valuations.6.5 <span class=\"_ _82\"> </span>Employee benefitsDefined-benefit plans are valued on the basis of uncertain events and actuarial assumptions which include, inter alia, the discount rates, the expected returns on the assets servicing the plans (where they exist), the level of future remuneration, mortality rates, the retirement age and future trends in the healthcare expenses covered.The main assumptions used to quantify defined-benefit plans are determined as follows: (i) the discount and inflation rates representing the base rates at which the obligation to employees might actually be fulfilled are based on the rates which mature on high-quality bonds and on inflation expectations; (ii) the level of future remuneration is determined on the basis of elements such as inflation expectations, productivity, career advancement and seniority; (iii) the future cost of healthcare services is determined on the basis of elements such as present and past trends in healthcare costs, including assumptions regarding the inflationary growth of costs, and changes in the health of the participating employees; and (iv) the demographic assumptions reflect the best estimates of trends in variables such as mortality, turnover<span class=\"_ _3\"></span>, invalidity and others in relation to the population of the participating employees.Differences in the value of net liabilities (assets) in employee benefit plans, arising due to changes in the actuarial assumptions used and the difference between the actuarial assumptions previously adopted and actual events, occur routinely and are called actuarial gains and losses. Actuarial gains and losses relating to defined-benefit plans are recognised in the comprehensive income statement. Actuarial assumptions are also used to determine obligations relating to other long-term benefits; to this end, the effects arising from changes to the actuarial assumptions or the characteristics of the ben<span class=\"_ _4\"></span>efit are fully recognised in the income statement.6.6 <span class=\"_ _82\"> </span>Fair valueCalculating the fair value of financial and non-financial instruments is a structured process featuring the use of complex evaluation methodologies and techniques that involve collecting up to date information from the reference markets and/or using internal input data.Similar to other estimates, calculating the fair value, albeit based on the best information available and on the adoption on adequate evaluation methodologies and techniques, it intrinsically features random elements and the exercising of professional judgement and could create forecasts with different values from those that will effectively be realised.6.7 <span class=\"_ _82\"> </span>Classification and measurement  of investments made for development<span class=\"_ _4\"></span>  <span class=\"_ _70\"> </span>and maintenance of proprietary  infrastructuresThe Snam Group makes significant investments for development and maintenance of its own infrastructures. Assessing the recoverability of the investments currently underway and the distinction of the costs as improvements, upgrades and transformations that increase the infrastructure and the expenses for ordinary maintenance and repairs which restore but do not increase the performance of the assets, includes valuation elements. These assessments are formulated on the basis of objective criteria that the Group has developed to facilitate an application consistent with its accounting policies.7ACCOUNTING ST<span class=\"_ _1\"></span>ANDARDS <span class=\"ls0 ws0\"> </span>PUBLISHED BY<span class=\"_ _3\"></span> THE IASB<span class=\"_ _0\"></span> BUT NOT<span class=\"_ _0\"></span> YET ENTERED<span class=\"_ _0\"></span> INT<span class=\"_ _0\"></span>O FORCE<span class=\"_ _0\"></span> New accounting standards or amendments to existing accounting standards issued by the IASB with an effective date after 31 December 2022 are set out below.

The </span>document applies to all insurance contracts and defines the principles of recognition, measurement, presentation and disclosure, replacing IFRS 4. The new standard requires a \u201cBuilding Block Approach\u201d (BBA)<span class=\"_ _0\"></span> based on expected cash flow and the specification of a \u201crisk adjustment\u201d and of a Contractual Service Margin (CSM) which represents expected profit from insurance contract. This margin is reported in the income statement in the period in which the insurance cover is provided. Moreover<span class=\"_ _0\"></span>, there are two alternative approaches in addition to the BBA which are the \u201cVariable Fee Approach\u201d (VF<span class=\"_ _0\"></span>A) and the Premium Allocation Approach (P<span class=\"_ _0\"></span>AA), applicable in specific cases. The standard also provides for a new method of presentation in the income statement, which presents the following separately: (i) \u201cinsurance revenues\u201d, (ii) \u201cinsurance service expenses\u201d and (iii) \u201cinsurance finance income or expenses\u201d. <span class=\"_ _8b\"> </span>The provisions contained in IFRS 17 are effective from financial years starting on or after 1 January 2023, and the directors are evaluating the possible effects associated with its introduction; however<span class=\"_ _0\"></span>, at the moment, it is reasonable to believe that the first application of these changes will not have a significant impact on the financial statements, also in light of the policy choices and exemptions allowed by the standard with reference to \u2018Insurance contracts issued to subsidiaries, associates and joint ventures\u2019.\u2022 <span class=\"_ _48\"> </span>Regulation No. 2022/357, issued by the European Commission on 2 March 2022, endorsed the regulatory provisions contained in the documents (i) \"<span class=\"ff63 ws14\">Disclosure </span>of Accounting P<span class=\"_ _0\"></span>olicies-Amendments to IAS 1 and IFRS Practice Statement 2<span class=\"ff6f\">\" and (ii) \"</span>Definition of Accounting Estimat<span class=\"_ _0\"></span>es-Amendments to IAS 8<span class=\"ff6f ls0\">\", </span>amendments published by the IASB on 12 Februar<span class=\"_ _4\"></span>y 2021. The amendments are intended to improve the disclosure of accounting policies so as to provide more useful information to investors and other primary users of financial statements and to help companies distinguish changes in accounting estimates from changes in accounting policies.

The amendment is a transition option relating to comparative information about financial assets presented at the date of initial application of IFRS 17. The amendment is intended to avoid temporary accounting mismatches between financial assets and liabilities of insurance contracts, and thus to improve the usefulness of comparative information for readers of financial statements. The amendments will apply from 1 January 2023, together with the application of IFRS 17.  The Group is analysing the standards and interpretations indicated, where applicable, in order to assess the effects of their application on the financial statements.

   "value": "Associates and joint ventures accounted for using the equity methodAn associate is an investee in which the Group has significant influence, i.e., the power to participate in determining the financial and operating policies of the associate company, without, however<span class=\"_ _0\"></span>, having control or 2joint control over it. It is assumed that the investor has significant influence (unless there is proof to the contrary) which is presumed to exist when the investment held is at least 20% of the exercisable voting rights.A joint venture is a joint arrangement in which the parties that hold joint control have rights to the net assets subject to the arrangement and, therefore, have an interest in the jointly controlled corporate vehicle.Equity investments in associates and joint ventures are measured using the equity method, whereby the investments are initially recognised at cost and subsequently adjusted to take account of:(i) <span class=\"_ _34\"> </span>the investor<span class=\"_ _4\"></span>\u2019s share in the economic results of the investee after the acquisition date;(ii) <span class=\"_ _e\"> </span>the investor\u2019s share of the other components in the comprehensive income statement of the investee.Dividends distributed by the investee are recognised net of the book value of the equity investment. For the purposes of applying the equity method, the adjustments provided for the consolidation process are taken into account (see also the previous point on fully consolidated subsidiaries).The sale of investment that results in loss of joint control or significant influence over the investee determines the recognition of the following in the income statement: (i) any capital gains or losses calculated as the difference between the consideration received and the corresponding fraction of the book value of the investment sold; (ii) the effect of the alignment to the fair value of any residual equity investment maintained; (iii) any amounts posted to other components in the comprehensive income statement relating to the investee entity that will be reclassified to the income statement. The value of any equity investment maintained, aligned with the relative fair value at the date of loss of joint control or significant influence, represents the new reference value for the successive valuation according to the applicable valuation criteria. If there is objective evidence of impairment, the Group performs an impairment assessment  by comparing the book value with the related recoverable amount and recognises the difference in the income statement under \u201cShare of profit or loss of investments accounted for using the equity method\u201d. If the Group\u2019s share of the loss exceeds the book value of the investment, the latter is written 2 <span class=\"_ _48\"> </span>Joint control is the contractual sharing of control pursuant to an agreement, which exists only where the unanimous consent of all the parties that share power is required for decisions relating to significant activities.off and any excess is recognised in a specific provision, if the investor is obliged to meet the legal or constructive obligations of the investee or otherwise cover its losses. When the reasons for the impairment losses no longer apply, equity investments are revalued up to the amount of the impairment losses entered, with the effect posted to the income statement under the above item.The parent company\u2019s share of any losses of the investee company, greater than the investment\u2019s book value, is<span class=\"_ _0\"></span> recognised in a special provision to the extent that the parent company is committed to fulfilling its legal or implied obligations to the investee, or<span class=\"_ _0\"></span>, in any event, to covering its losses.",

T<span class=\"_ _0\"></span>o determine whether a particular set of acquired assets and activities meets the definition of a \u201cbusiness\u201d, the Group examines whether that set comprises, at least, a production factor and a substantial process and whether it has the ability to generate production. Business combinations are accounted for by applying the acquisition method, whereby the consideration transferred at the date of acquisition of control is equal to the fair value of the assets transferred, the liabilities incurred or taken on, and any equity instruments issued.<span class=\"_ _0\"></span> The consideration transferred also includes the current value of any deferred fixed payments and the fair value of any contingent considerations (e.g earn-outs). If the<span class=\"_ _0\"></span> contingent consideration meets the definition of an equity instrument, it is classified as shareholders\u2019 equity and is not measured thereafter<span class=\"_ _0\"></span>. Other contingent considerations are recognised as a liabilities and are measured at fair value at each financial year-end; changes in fair value are<span class=\"_ _0\"></span> recognised in the income statement.Costs directly attributable to the transaction, other than those related to the issue of debt or equity instruments, are recognised in the income statement when they are incurred.The shareholders\u2019 equity of these associate companies is determined by attributing to each asset and liability its fair value at the date of acquisition of control. If positive, any difference from the consideration transferred is posted to the asset item \u201cGoodwill\u201d; if negative, it is posted instead to the income statement.Where total control is not acquired, the share of equity attributable to minority interests is determined based on the share of the current values attributed to assets and liabilities at the date of acquisition of control, net of any goodwill (the \u201cpartial goodwill method\u201d). Alternatively, the full amount of the goodwill generated by the acquisition is recognised, therefore also taking into account the portion attributable to minority interests (the \u201cfull goodwill method\u201d). In this case, non-controlling interests are expressed at their total fair value, including the attributable share of goodwill. The choice of how to determine goodwill (Partial goodwill method or full goodwill method) is based on each individual business combination transaction.If control is assumed in successive stages, the consideration transferred is determined by adding together the fair value of the equity investment previously held in the acquired company and the amount paid to acquire the additional equity investment. The difference between the fair value of the previously held equity investment (redetermined at the time of acquisition of control) and the relative book value is posted to the income statement. Upon acquisition of control, any components previously recognised under other components in the comprehensive income statement are posted to the income statement or to another item of shareholders\u2019 equity, if no provisions are made for classification in the income statement.When the values of the assets and liabilities of the acquired entity are determined provisionally in the financial year in which the business combination is concluded, the figures recorded are adjusted, with retroactive effect, no later than 12 months after the acquisition date, to take into account new information about facts and circumstances in existence at the acquisition date.Business combinations involving entities under joint controlBusiness combinations involving companies that are definitively controlled by the same company or companies before and after the transaction, and where such control is not temporary, are classed as \u201cBusiness combinations of entities under common control\u201d, whose accounting is not specifically disclosed in IFRSs.  In the absence of a reference accounting standard, the selection of an accounting standard for such transactions, for which a significant influence on future cash flows cannot be established, is guided by the principle of prudence, which leads to the application of the criterion of continuity of values of the net assets acquired. The assets are measured at the book values from the financial statements of the companies being acquired (or the vendor company) before the transaction or<span class=\"_ _0\"></span>, alternatively, at the values from<span class=\"_ _0\"></span> the consolidated financial statements of the common ultimate parent.With regard to the sale of business, the treatment of the difference between the contractually defined consideration and the carrying amounts of the transferred business is differentiated depending on the entities involved in the transfer<span class=\"_ _0\"></span>.With regard to contributions involving businesses under common control, on the other hand, irrespective of the pre-existing investment relationship, the transferee entity recognises the transferred business at its historical carrying value, increasing its own equity by an equal amount; the transferring entity shall recognise the investment in the transferee entity at an amount equal to the increase in the latter\u2019s shareholders\u2019 equity. This accounting treatment refers to the proposal by Assirevi in the Preliminary Guidelines on IFRS (OPI No. 1 Revised) - \u201c<span class=\"_ _3\"></span>Accounting treatment of business combinations of entities under common control in the separate and consolidated financial statements\u201d issued in October 2016.<span class=\"ls0 ws0\"> </span>Accounting treatment of put options written on the shares of subsidiariesTherefore, if the Group does not have the unconditional right to avoid delivery of cash or other financial instruments when a put option on shares in subsidiaries is exercised, a financial liability equal to the current value of the option exercise price is recognised and subsequent changes in the financial liability are recognised in the income statement. The same accounting treatment is applicable when, in addition to a put option, there is also the simultaneous presence of a symmetrical call option, the so-called \u201csymmetrical put and call options related to non-controlling interest\u201d.Snam considers that shares subject to put options (or symmetrical put and call options) have already been acquired by the Group, in cases where the economic benefits and risks associated with the actual ownership of the shares do not remain with the minority shareholders; therefore, in such circumstances, it does not recognise minority interests in the consolidated financial statements.",

When there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of property, plant and equipment or intangible assets with a finite useful life, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs(see paragraph 5.8 \u201cMeasurement at fair value\u201d), or the value in use, whichever is greater<span class=\"_ _3\"></span>.The recoverable amount, in the value in use configuration, is determined by discounting projected cash flows resulting from the use of the asset and, if they are significant and can be reasonably determined, from its sale at the end of its useful life, net of any disposal costs.With reference to the T<span class=\"_ _0\"></span>ransportation (Snam Rete Gas), Regasification (LNG) and Storage (Stogit) C<span class=\"_ _0\"></span>GUs, the recoverable value was defined as corresponding to the estimated value of the Net Invested Capital recognised to these assets for tariff 5purposes (R<span class=\"_ _4\"></span>AB - Regulatory Asset Base) by the Regulatory Authority for Energy, Networks and the Environment (ARER<span class=\"_ _4\"></span>A), net of the flat<span class=\"_ _0\"></span>-rate components, of the Employee Severance Indemnity (TFR) and of the contributions received.The measurement is made on a per-asset basis or for the smallest identifiable set of assets that, through its own continuous use, generates cash inflows that are largely independent of those of other assets or groups of assets (Cash Generating Units - CGUs). Expected cash flows are determined on the basis of reasonable and documentable assumptions representative of the best estimate of the future economic conditions of the asset or groups of assets, giving greater importance to indications from the outside. Discounting is done at a rate reflecting current market conditions for the time value of money and specific risks of the asset not reflected in the estimated cash flows. If the book value of the asset or CGU is greater than its recoverable amount, an impairment loss is recognised in the income statement; a CGU\u2019s impairment losses are first recognised as a reduction in the book value of any goodwill (see next point \u201cImpairment of goodwill and intangible assets not yet available for use\u201d) allocated to it and then as a reduction in the book value of the other assets of the CGU, in proportion to their respective carrying amounts. The book value of each Cash Generating Unit (or grouping of CGUs), consistently with the prevailing valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test<span class=\"_ _4\"></span>.If the conditions for a previously effected impairment no longer apply, the book value of the asset (except for goodwill) is restored with recognition in the income statement (recovery of value), within the limits of the net book value that the asset in question would have had if the impairment had not been carried out and any related amortisation had been carried out.    If certain specific assets held by the Group are affected by unfavourable operating or economic conditions that may compromise their ability to contribute to the realisation of cash flows, they may be subject to an independent recoverability analysis and impaired, if necessary. Impairment of goodwill,  intangible assets with an indefinite useful life and intangible assets not yet available for use.The recoverability of the book value of goodwill, of intangible assets with an indefinite useful life and intangible assets not yet available for use is tested at least annually, and in any case when events occur leading to an assumption of<span class=\"_ _0\"></span> impairment.Pursuant to the provisions of IFRS 3, in the context of business combinations, the acquirer<span class=\"_ _0\"></span>, at the acquisition date, recognises all assets, liabilities and identifiable contingent liabilities under the acquisition at their fair values; any remaining positive difference with respect to the acquisition cost is recognized in the asset item Goodwill, and any negative difference is recognised in the income statement.5 <span class=\"_ _48\"> </span>The RAB is the reference basis for the determination of the ser<span class=\"_ _4\"></span>vice tariffs and, therefore, of the cash flows generated by the activities. The value of the RAB is defined through the historical cost method revalued as regards the Fixed capital, and on a flat rate basis for the working capital, the employee severance indemnity and, with reference to the storage segment, the provision for decommissioning and site restoration.For the purpose of the impairment test, goodwill is allocated, as from the date of acquisition, to each Cash Generating Unit, or group of CGUs, that is expected to benefit from the synergies of the combination. After its initial recognition, goodwill is not amortised but is instead subject to a recoverability test at least annually by determining the recoverable value of the CGU or group of CGUs to which it is allocated (following the procedures described in the note \u201cImpairment of tangible and intangible assets of finite useful life\u201d); this is then compared to the book value of the CGU itself (or group of CGUs). The book value of each Cash Generating Unit<span class=\"_ _0\"></span> (or grouping of CGUs), consistently with the prevailing<span class=\"_ _0\"></span> valuation practice, is equal to the respective Net Invested Capital recorded at the level of Snam\u2019s consolidated financial statements at the reference date for carrying out the impairment test.When the book value of the CGU (or group of CGUs<span class=\"_ _0\"></span>), including the goodwill attributed to it, exceeds the recoverable value, the difference is subject to impairment, which is attributed by priority to the goodwill up to its amount; any surplus in the impairment with respect to the goodwill is attributed pro rata to the book value of the assets constituting the CGU (or group of CGUs<span class=\"_ _0\"></span>). Goodwill write-downs are not reversed, even if the reasons for the write- down no longer apply in subsequent years.<span class=\"ls0\"> </span>Reduction in value of Equity investmentsWhen there are indications that an impairment loss may exist or when events occur leading to the assumption of impairment of investments, their recoverability is tested by comparing the book value with the related recoverable value, which is the fair value, net of disposal costs (see paragraph 5.8 \u201cMeasurement at fair value\u201d), and the value in use, determined through the application of the 6Dividend Discount Model (DDM) or Discounted Cash Flow(DCF) method, (the present value of the expected cash flows is determined in accordance with the provisions of the previous paragraph \u201cImpairment of tangible and intangible assets with a finite useful life\u201d). The application of the Dividend Discount Model (DDM) provides that the recoverable value, in the configuration of the value in use, is determined by discounting the expected dividend flows on the basis of the forecast plans of the investee companies drawn up according to reasonable and documentable assumptions, discounted at the cost of the capital (Ke) which includes an<span class=\"_ _0\"></span>y specific risks not reflected in the estimated cash flows.6 <span class=\"_ _48\"> </span>If the Discounted Cash Flow (DCF) method is used, the results are adjusted for the respective net financial positions.",

The Business Model for financial asset management determines whether cash flows will come from (i) the collection of cash under the contract, (ii) the sale of financial assets, or (iii) both.The test, aimed at determining whether the instrument generates cash flows representing solely payments of principal and interest (so-called \"Solely Payments of Principal and Interest\") and is referred to as the \"SPPI test\" and is performed at the individual instrument level.Financial assets \u2013 Subsequent measurementFinancial assets measured at amortised costFinancial assets at amortized cost mainly include trade receivables, other receivables, and financial receivables. Financial assets at amortized cost are held as part of a business model whose objective is to collect cash flows in accordance with contractual terms, represented exclusively by principal and interest on principal to be repaid at specific dates (so-called Hold T<span class=\"_ _0\"></span>o Collect business model).These assets, as indicated, are initially recognized at fair 8value, adjusted for transaction costs where appropriate, and subsequently measured at amortized cost using the effective interest rate.According to the amortised cost method the initial book value is then adjusted to account for repayments of principal, any impairments for credit losses and the amortisation of the difference between the repayment amount and the initial book value.Amortisation is carried out using the effective internal interest rate, which represents the rate that would make the present value of projected cash flows and the initial recognition value equal at the time of the initial recording.Financial assets valued at the amortised cost are presented in the statement of financial position net of the related 8 <span class=\"_ _48\"> </span>Except for trade receivables where, if they lack a significant financial component, they are initially recognized at transaction price (as defined in IFRS 15).provision for impairment losses.T<span class=\"_ _0\"></span>ransferred financial assets are derecognised from the balance sheet assets when the contractual rights to obtain the cash flows associated with the financial instrument expire, or all risks and rewards associated with the transferred receivable are transferred to a third party in accordance with the guidance on derecognition of financial assets set forth in IFRS 9.For financial assets measured at amortized cost, interest income determined on the basis of the effective interest rate, foreign exchange differences, and write-downs (including gains and losses from derecognition or modification of the asset) are recognized in the income statement.With specific reference to trade receivables, in order to measure Expected Credit Losses (\"ECLs\"), a valuation is made using the so-called \"simplified approach\" provided by IFRS 9, or - by virtue of the absence of a significant financial component - by estimating expected losses over the life of the receivable (\"lifetime ECLs<span class=\"_ _0\"></span>\").The assessment of the recoverability of trade receivables is made on both an individual and collective basis depending on the type of counterparty and whether there is reasonable and demonstrable information available to make an assessment at the individual instrument level.The group applies a specific definition of default, determined<span class=\"_ _4\"></span> by taking into account the characteristics of the operating segments to which the subsidiaries belong as well as the riskiness of the receivables and customers being assessed. Therefore, beyond the time limit of default, trade receivables<span class=\"_ _4\"></span> are assumed to be impaired (i.e. credit<span class=\"_ _0\"></span>-impaired).In particular<span class=\"_ _0\"></span>, expected losses are generally determined on the basis of the product between: (i) <span class=\"_ _16\"> </span>the amount of exposure to the counterparty at the time of default (so-called 'Exposure At Default' or 'EAD');(<span class=\"_ _4\"></span>ii<span class=\"_ _4\"></span>)<span class=\"_ _4\"></span> <span class=\"_ _8\"> </span>the probability that the counterparty will default on its<span class=\"_ _4\"></span> payment obligations (so-called Probability of Default or PD); (iii) the estimate, in percentage terms, of the amount of credit that will not be recovered in the event of default (so-called Loss Given Default or L<span class=\"_ _0\"></span>GD).With regard to the ECL parameters listed above, the group considers the following assumptions:(i) <span class=\"_ _16\"> </span>PD is determined according to the type of counterparty on the basis of:\u2022 <span class=\"_ _29\"> </span>qualified external providers (e.g. for listed companies);\u2022 <span class=\"_ _29\"> </span>regional ratings (e.g. for public administration<span class=\"_ _0\"></span>) by leading rating agencies;\u2022 <span class=\"_ _29\"> </span>average default rate calculated for groups of customers broken down by common credit risk (so-called 'cluster') considering historical data over a period of at least 24 months; (ii) <span class=\"_\"> </span>the LGD is obtained on the basis of market standards that assess the recovery rate of the exposure depending on the region and sector of the counterparty (e.g. corporate, government and retail);(iii) the E<span class=\"_ _4\"></span>AD is determined to be equal to the face value of the claim at the valuation date, less any related mitigating factor<span class=\"_ _0\"></span>, including any amounts pledged as collateral.In the case of credit exposures in litigation and where detailed information is available on the recoverability of the exposure, analytical assessments are performed in order to better reflect the actual riskiness of the position in the determination of expected losses. The exposures for which credit recovery actions have been activated through legal/court proceedings are defined as litigation.Impairments of trade receivables and other receivables are recognised in the income statement, net of any write-backs, under the item \u201cOther operating expenses\u201d.Financial assets, measured at fair value with effects recognized in other comprehensive income (FVTOCI) Credits and Debt Instrument<span class=\"_ _4\"></span>sIf present, financial assets representing loans and debt instruments whose business model envisages the possibility of both collecting the contractual cash flows and realizing their value through sale (so-called Hold to Collect and Sell, or Mixed, Business Model) are measured at fair value with the effects charged to OCI (so-called FV<span class=\"_ _4\"></span>TOCI). Under this measurement criterion, interest income, calculated using the effective interest rate, exchange rate differences and impairment losses are recognized in the income statement; changes in the fair value of the instrument are recognized in equity, among other components of comprehensive income.When a financial asset is derecognized (e.g., upon sale), the cumulative amount of changes in fair value, up to that point recognized in OCI, are reclassified to the income statement.The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\" - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.Financial assets measured at fair value with effects charged to the income statementCredits and Debt Instrument<span class=\"_ _4\"></span>sThe category of financial assets measured at fair value through profit or loss (so-called FV<span class=\"_ _4\"></span>TPL) includes:\u2022 <span class=\"_ _29\"> </span>financial assets with cash flows that are not represented exclusively by principal and interest payments, regardless of the business model (financial assets that do not pass the SPPI test);\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets held for trading because they are </span>purchased or held primarily for the purpose of being sold (financial assets that pass SPPI test but held under a so-called Business Model T<span class=\"_ _0\"></span>rading)\u2022 <span class=\"_ _33\"> </span><span class=\"ws0\">financial assets for which the entity voluntarily adopts </span>the so-called Conditional F<span class=\"_ _0\"></span>air Value Option (these are<span class=\"_ _0\"></span> financial assets that pass the SPPI T<span class=\"_ _0\"></span>est and for which despite the Business Model being Hold to Collect or Mixed, the company decides to exercise the option<span class=\"_ _0\"></span> granted by IFRS 9 that allows the financial asset to be valued at FV<span class=\"_ _4\"></span>TPL).Where present, credits arising from invoice rebates to customers in the energy efficiency business (pertaining to so-called \"Ecobonus\" and \"Superbonus\") - and which<span class=\"_ _0\"></span> are converted into tax credits - if held with the objective of realizing cash flows through sale (so-called \"Other\" Business Model) are measured at fair value with the effects charged to the income statement (so-called FV<span class=\"_ _4\"></span>TPL).The rationale behind the determination of fair value is explained in Note No. 5.8 \"Significant Accounting Policies\"<span class=\"_ _0\"></span> - \"F<span class=\"_ _0\"></span>air Value Measurement,\" respectively.",

Under the scope of the strategy and objectives defined for risk management, the qualification of transactions as hedging requires: (i) the verification of the existence of an economic relationship between the object hedged and the hedging instrument for the purpose of offsetting the changes in value and ensuring this offsetting capacity is not invalidated by the level of counterparty credit risk; (ii) the definition of a hedge ratio consistent with the risk management objectives, under the scope of the risk management strategy defined, where necessary activating the appropriate rebalancing actions. The amendments of the risk management objectives, the disappearance of the conditions indicated previously for the qualification of transactions as hedging or the activation of rebalancing operations cause the total or partial prospective discontinuation of the hedge.In order to qualify a transaction as a hedge, at the start of the hedge a formal document is prepared that illustrates the strategies and objectives of the risk management and identifies the hedging instrument, the instrument hedged, the nature of the risk hedged and the methods through which the evaluation of whether the hedge relationship satisfies the hedge effectiveness requirements takes place.When hedging derivatives hedge the risk of changes in the fair value of the hedged instruments (\u201cfair value hedge\u201d; e.g. hedge of the risk of fluctuations in the fair value of fixed-rate assets/liabilities), the derivatives are recognised<span class=\"_ _0\"></span> at fair value with attribution of the effects on the income statement; by the same token, the hedged instruments are adjusted to reflect in the income statement the changes in fair value associated with the hedged risk, regardless of the provision of a different valuation criterion generally applicable to the instrument type.The group subscribes to derivative instruments to cover the risk of changes in cash flows (cash flow hedges) as a result of fluctuations in interest rate or exchange rates. Changes in the fair value of hedging derivatives considered effective are initially recognised in the shareholders\u2019 equity reserve relating to other components in the comprehensive income statement and are subsequently reclassified to profit or loss in line with the economic effects produced by the hedged transaction. In the case of hedging future transactions that involve the recording of a non-financial asset or liability, the cumulative variations of the fair value of the hedge derivatives, recognised in shareholders\u2019 equity, are recognised in the adjustment of the book value of the non- financial asset/liability subject to hedging (basis adjustment).The ineffective portion of the hedge and the changes in the fair value of derivatives that do not meet the qualifying conditions for hedging are recognised in the income statement.",

A<span class=\"_ _0\"></span> fair value measurement also assumes that the asset or liability would be traded on the main market or<span class=\"_ _3\"></span>, failing that, on the most advantageous market to which the Company has access.The fair value of a non-financial asset is determined by considering the capacity of market operators to<span class=\"_ _0\"></span> generate economic benefits by putting the asset to its maximum and best use or by selling it to another market participant capable of using it in such a way as<span class=\"_ _0\"></span> to maximise its value. The maximum and best use of an asset is determined from the perspective of market<span class=\"_ _0\"></span> operators, also hypothesising that the company intends<span class=\"_ _0\"></span> to put it to a different use; the current use by the company of a non-financial asset is assumed to be the maximum and best use of this asset, unless the market or other factors suggest that a different use by market<span class=\"_ _0\"></span> operators would maximise its value.The fair-value measurement of a financial or non-financial liability, or of an equity instrument, takes<span class=\"_ _0\"></span> into account the quoted price for the transfer of an identical or similar liability or equity instrument; if this quoted price is not available, the valuation of a corresponding asset held by a market operator as at<span class=\"_ _0\"></span> the valuation date is taken into account. The fair value of financial instruments considers the credit risk of the counterparty for financial assets (through a \u201cCredit<span class=\"_ _0\"></span> Valuation Adjustment\u201d - CV<span class=\"_ _0\"></span>A) and the entity\u2019s own risk of default for financial liabilities (through a \u201cDebit Valuation<span class=\"_ _0\"></span> Adjustment\u201d - DV<span class=\"_ _3\"></span>A).When determining fair value, a hierarchy is set out<span class=\"_ _0\"></span> consisting of criteria based on the origin, type and quality of the information used in the calculation. This classification aims to establish a hierarchy in terms of the<span class=\"_ _0\"></span> reliability of the fair value, giving precedence to the use of parameters that can be observed on the market and that reflect the assumptions that market participants<span class=\"_ _0\"></span> would use when valuing the asset/liability.<span class=\"_ _0\"></span> The fair value hierarchy includes the following levels:\u2022 <span class=\"_ _29\"> </span>level 1: listed prices (unadjusted) in active mark<span class=\"_ _0\"></span>ets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;\u2022 <span class=\"_ _29\"> </span>level 2: inputs, other than the quoted prices included in Level 1, that can be directly or indirectly observed for the assets or liabilities to be valued;\u2022 <span class=\"_ _29\"> </span>level 3: inputs for assets or liabilities that are not based on observable market data.In the absence of available market quotations, the fair value is determined by using valuation techniques suitable for each individual case that maximise the use of significant observable inputs, whilst minimising the use of non-observable inputs.",

Provisions are recorded at the value representing the best estimate of the amount that the Company would reasonably pay to fulfil the obligation or to transfer it to third parties at the end of the reporting period.Provisions related to contracts with valuable consideration are recorded at the lower of the cost necessary to fulfil the obligation, less the expected economic benefits arising from the contract, and the cost of terminating the contract.When the financial impact of time is significant, and the payment dates of the obligations can be reliably estimated, the provision is calculated by discounting the anticipated cash flows in consideration of the risks associated with the obligation at the Company\u2019s average debt rate; the increase in the provision due to the passing of time is posted to the income statement under \u201cFinancial income (expense)\u201d.When the liability is related to items of property, plant and equipment (e.g. decommissioning and site restoration), the provision is recognised as a counter-entry to the related asset, and posting to the income statement is accomplished through amortisation. The costs that the Company expects to incur to initiate restructuring programmes are recorded in the period in which the programme is formally defined, and the parties concerned have a valid expectation that the restructuring will take place.Provisions are periodically updated to reflect changes in cost estimates, selling periods and the discount rate; revisions in provision estimates are allocated to the same item of the income statement where the provision was previously reported or<span class=\"_ _0\"></span>, when the liability is related to property, plant and equipment (e.g. site dismantling and restoration), as a contra-entry to the related asset, up to the book value; any surplus is posted to the income statement.The notes to the financial statements describe contingent liabilities represented by: (i) possible (but not probable) obligations resulting from past events, the existence of which will be confirmed only if one or more future uncertain events occur which are partially or fully outside the Company\u2019s control; and (ii) current obligations resulting from past events, the amount of which cannot be reliably estimated, or the fulfilment of which is not likely to involve costs.Contingent assets, or possible assets that result from past events and whose existence will only be confirmed when one or more uncertain future events, not totally under the control of the business, occur or do not occur<span class=\"_ _0\"></span>, are not recognised unless obtaining the related benefits is virtually certain.

This condition is regarded as fulfilled when the sale is highly probable and the asset or discontinued operations are available for immediate sale in their current condition. In the case of a programme for the sale of a subsidiary that results in loss of control, all assets and liabilities of that subsidiary are classified as held for sale, regardless of whether a non-controlling investment is maintained following the sale. V<span class=\"_ _0\"></span>erification of compliance with the terms and conditions provided for classification of an item as held for sale requires management to make subjective valuations formulating reasonable and realistic assumptions based on the information available to it. Immediately prior to classification as held for sale, the assets and liabilities included in a disposal group are measured in accordance with the accounting standards applicable to them. Subsequently, non- current assets held for sale are not amortised or depreciated and are measured at the lower of book value and related fair value, less any sales costs (see paragraph 5.8 \u201cF<span class=\"_ _0\"></span>air<span class=\"_ _0\"></span>-value measurements\u201d above).The classification of investments accounted for using the equity method as held for sale implies the suspension of the application of this valuation criterion. Any negative difference between the book value of the non-current assets and their fair value less selling costs is posted to the income statement as an impairment loss; any subsequent recoveries in value are recognised up to the amount of the previously recognised impairment losses, including those recognised prior to the asset being classified as held for sale.Non-current assets and disposal group- related assets and liabilities held for sale are recognised in the statement of financial position separately from the group\u2019s other assets and liabilities.Non-current assets and disposal groups, classified as held for sale, constitute a discontinued operation if<span class=\"_ _0\"></span>, alternatively:  (i) <span class=\"_ _16\"> </span>they represent a significant autonomous business unit or a significant geographical area of operations; (ii) <span class=\"_\"> </span>they are part of a plan to dispose of a significant autonomous business unit or a significant geographical area of operations;  (iii) they relate to a subsidiar<span class=\"_ _4\"></span>y acquired exclusively to be sold.

   "value": "5.1<span class=\"_ _3\"></span>1 RevenueThe recognition of revenue from contracts with customers is based on the following five steps: (i) identification of the contract with the customer; (ii) identification of the performance obligation, represented by the contractual commitment to transfer goods and/or services to a customer; (iii) calculating of the transaction\u2019s price; (iv) allocating of the transaction price to the performance obligations identified based on the stand alone sales price of each of the goods or services; (v) measuring the revenue when the performance obligation is met, i.e. at the time of the transfer to the customer of the goods or services promised; the transfer is considered to be completed when the customer obtains control of the goods or service, which can take place over time or at a point in time.Revenues are measured for the amount equal to the fair value of the consideration which the business believes it has the right to in exchange for the goods and/or services promised to the customer<span class=\"_ _0\"></span>, with the exception of amounts collected on behalf of third-parties. If there is a variable consideration, the business estimates the amount of the consideration it shall have the right to in exchange for the transfer of goods and/or services promised to the customer;<span class=\"_ _4\"></span> specifically, the amount of the consideration can vary in the presence of discounts, incentives, concessions on the price, performance bonuses, penalties or if the actual price depends on certain future events taking place or not.Revenues from the Snam Group\u2019s ordinary operations mainly consist of services relating to the transportation, dispatching and storage of natural gas and the regasification of liquefied natural gas, which are recognised in the financial statements over the period in which the service is provided, whether the ser<span class=\"_ _4\"></span>vices are \u201cregulated\u201d or \u201cnon-regulated\u201d. The recognition of revenues for regulated services is conditioned and influenced by the regulatory framework defined by ARER<span class=\"_ _4\"></span>A (Autorit\u00e0 di Regolazione per Energia Reti e Ambiente \u2013 Regulatory Authority for Energy Networks and the Environment). Therefore, the economic conditions of the services provided are defined through regulator<span class=\"_ _4\"></span>y schemes and not on a negotiated basis. The revenue recognised in the income statement coincides with that recognised by the regulator (so-called \u201crevenue cap\u201d). As regards the transportation business segment, the difference between the revenue recognised by the regulator (so- called \u201crevenue cap\u201d) and that actually accrued is recorded, if positive, in the item of the statement of financial position \u201cTrade payables and other payables\u201d and, in the item \u201cTrade and other payables\u201d, as it will be subject to cash settlement with the Cassa per i Servizi Energetici e Ambientali (CSEA). In the Regasification and Storage segments any difference between the revenue recognised by the regulator and the accrued revenue is recognised in the balance sheet item \u201cTrade and other receivables\u201d, if positive, and in the item \u201cTrade payables and other payables\u201d, if negative, inasmuch as it will be subject to cash settlement with the Energy and Environmental Services Fund (CSEA).Non-regulated revenues mainly involve: (i) considerations for the construction of biogas and biomethane plants; (ii) technical- specialist services to unconsolidated foreign companies; (iii) the provision of services relating to energy efficiency projects; (iv) income from the rental and maintenance of fibre optic telecommunication cables; (v) the sale of CNG compressors for motor transport. The recognition of these revenues takes place over the service provision period.By virtue of the principle of neutrality defined by applicable regulations, transactions carried out on the balancing market generate neither costs nor revenue, as they are mere pass-through items. Any (positive or negative) differences from the usage of different prices for the transactions above will be neutralized by recognizing an asset or liability for CSEA<span class=\"_ _4\"></span>, given that these differences are equalized by the latter<span class=\"_ _0\"></span>.",

Deferred tax assets are recognised when their recovery is considered probable; specifically, the recoverability of deferred tax assets is considered probable when taxable income is expected to be available in the period in which the temporary difference is cancelled, allowing the activation of the tax deduction.

   "value": "6ASSUMPTIONS AND<span class=\"_ _0\"></span> <span class=\"_ _4\"></span>UNCERT<span class=\"_ _32\"></span>AINTIES IN ESTIMA<span class=\"_ _3\"></span>TES  The application of generally accepted accounting principles for the preparation of financial statements involves management making accounting estimates based on complex and/or subjective judgements, estimates based on past experience and assumptions regarded as reasonable and realistic on the basis of the information known at the time of the estimate. The use of these accounting estimates has an influence on the book value of the assets and liabilities and on the information about potential assets and liabilities at the reporting date, as well as the amount of revenue and costs in the reference period. The actual results may differ from the estimated results owing to the uncertainty that characterises the assumptions and the conditions on which the estimates are based. Details are given below about the critical accounting estimates involved in the process of preparing the financial statements and interim reports, since they involve a high degree of recourse to subjective judgements, assumptions and estimates regarding matters that are by nature uncertain. Any change in the conditions forming the basis of the judgements, assumptions and estimates used could have a significant impact on subsequent results.6.1 <span class=\"_ _82\"> </span>Impairment of non-financial assetsNon-financial assets are impaired when events or changes in circumstances give cause to believe that the book value is not recoverable. The events that can lead to an impairment of assets include changes in business plans, changes in market prices or reduced use of plants. The decision on whether to apply an impairment and the quantification of any such impairment depend on the Company\u2019s management assessment of complex and highly uncertain factors, such as future price trends, the impact of inflation and technological improvements on production costs, production profiles and conditions of supply and demand. The impairment is determined by comparing the book value with the related recoverable value, represented by the greater of the fair value, net of disposal costs, and the usage value, determined by discounting the expected cash flows deriving from the use of the asset, or represented by the R<span class=\"_ _4\"></span>AB in the regulated business segments. The expected cash flows are quantified in the light of the information available at the time of the estimate, on the basis of subjective judgements regarding future trends in variables \u2013 such as prices, costs, the rate of growth of demand and production profiles \u2013 and are discounted using a rate that takes account of the risk inherent to the asset concerned. The rationale behind the impairment testing used by management in relation to property plant and machinery, intangible assets, goodwill and investments<span class=\"_ _4\"></span> accounted for using the equity method are illustrated respectively in note 8 \u201c\u2018Property, plant and equipment\u2019\u201d, note 9 \u201c\u2018Intangible assets and goodwill\u201d and note 10 \u201cInvestments accounted for using the equity method\u201d.6.2 <span class=\"_ _82\"> </span>Impairment of financial assetsAt each reporting date, assessments are made of the recoverability of financial assets in order to determine the value of expected credit losses (ECL).In particular<span class=\"_ _0\"></span>, the valuation of trade receivables is carried out using the simplified approach established by IFRS 9, which involves estimating the ECL over the life of the receivable. In these cases, the impairment is generally based on the expected credit loss model and is carried out through the use of both qualified external providers and by means of an analysis of observed historical data with respect to credit recoverability; analysis performed for homogeneous categories of counterparties. On the other hand, for certain categories of credits characterised by peculiar risk elements (e.g. litigation or credit recovery practices through legal/judicial proceedings), specific assessments are carried out on individual credit positions. The logic behind the expected credit loss model is explained in Note 5 \"Significant accounting standards\" - \"Non-derivative Financial Assets -Receivables and Debt securities\", respectively.6.3 <span class=\"_ _82\"> </span>Provisions for risks and charges  Provision for decommissioning and site restorationThe Snam Group incurs significant liabilities associated with obligations to remove and dismantle plants or parts of plants. Estimating future dismantling and restoration costs is a complex process and requires the assessment and judgement of the Company\u2019s management in placing a value on the liabilities that will be incurred many years in the future for compliance with dismantling and restoration obligations, which often cannot be fully defined by laws, administrative regulations or contractual clauses. In addition, these obligations are affected by constant changes in technology and in dismantling and restoration costs, as well as the constant growth of political and public awareness regarding matters of health and protection of the environment.The criticality of estimates of dismantlement and restoration costs also depends on the accounting method used for these costs, for which the current value is initially capitalised together with the cost of the asset to which they relate, offset against the provision for risks and charges. Thereafter<span class=\"_ _0\"></span>, the value of the provision for risks is updated to reflect the passing of time and any changes in the estimate as a result of changes in expected cash flows, the timing of their realisation and the discount rates applied.The calculation of the discount rate to be used both in the initial valuation of the cost and in subsequent valuations is the result of a complex process which involves subjective judgements on the part of the Company\u2019s management. Environmental liabilitiesThe Snam Group is subject, in relation to its activities, to numerous laws and regulations on environmental protection at European, national, regional and local level, including the laws which implement international conventions and protocols relating to the activities carried out. With reference to this legislation, when it is probable that the existence and amount of a large liability can be reliably estimated, provisions are made for the associated costs.The group does not currently believe that the financial statements will suffer particularly significant adverse effects due to non-compliance with environmental regulations, also considering actions already undertaken, but it cannot be ruled out with certainty that Snam may incur further<span class=\"_ _0\"></span>, possibly significant, costs or liabilities, since current knowledge says it is impossible to predict the effects of future developments, taking into account also the following aspects: (i) the possible emergence of contamination; (ii) the outcome of the refurbishment in progress and to be followed and the other possible effects arising from the application of the laws in force; (iii) the possible effects of new laws and regulations for environmental protection; (iv) the effects of any technological innovations for environmental reclamation; (v) the possibility of disputes and the difficulty of determining the possible consequences, also in relation to the liability of other parties and to possible compensation payments.Provisions for legal and tax disputesThe estimation of the group\u2019s provisions for these purposes is the result of a complex process involving subjective judgements by Company management.6.4 <span class=\"_ _82\"> </span>Investments and business  combinationsV<span class=\"_ _0\"></span>erification of the existence of control, joint control, considerable influence over another entity as well as, in the case of joint operations, verification of the existence of enforceable rights and obligations requires Corporate Management to exercise professional judgement taking into consideration the characteristics of the corporate structure and agreements between the parties as well as other facts and circumstances that are relevant for the purpose of this check. Similar considerations also apply in cases of a planned change in status following a loss of control, joint control or connection with the possible need to activate the classification as \u201cassets held for sale/discontinued operation\u201d.The reporting of business combination transactions involves the allocation to the assets and liabilities of the acquired company of the difference between the acquisition cost and the net book value. For the majority of assets and liabilities, the attribution of the difference is carried out by recognising the assets and liabilities at their fair value. The unallocated portion, if positive, is recognised as goodwill; if negative, it is allocated to the income statement. In the allocation process, the Snam Group draws on the available information and, for the most significant business combinations, on external valuations.6.5 <span class=\"_ _82\"> </span>Employee benefitsDefined-benefit plans are valued on the basis of uncertain events and actuarial assumptions which include, inter alia, the discount rates, the expected returns on the assets servicing the plans (where they exist), the level of future remuneration, mortality rates, the retirement age and future trends in the healthcare expenses covered.The main assumptions used to quantify defined-benefit plans are determined as follows: (i) the discount and inflation rates representing the base rates at which the obligation to employees might actually be fulfilled are based on the rates which mature on high-quality bonds and on inflation expectations; (ii) the level of future remuneration is determined on the basis of elements such as inflation expectations, productivity, career advancement and seniority; (iii) the future cost of healthcare services is determined on the basis of elements such as present and past trends in healthcare costs, including assumptions regarding the inflationary growth of costs, and changes in the health of the participating employees; and (iv) the demographic assumptions reflect the best estimates of trends in variables such as mortality, turnover<span class=\"_ _3\"></span>, invalidity and others in relation to the population of the participating employees.Differences in the value of net liabilities (assets) in employee benefit plans, arising due to changes in the actuarial assumptions used and the difference between the actuarial assumptions previously adopted and actual events, occur routinely and are called actuarial gains and losses. Actuarial gains and losses relating to defined-benefit plans are recognised in the comprehensive income statement. Actuarial assumptions are also used to determine obligations relating to other long-term benefits; to this end, the effects arising from changes to the actuarial assumptions or the characteristics of the ben<span class=\"_ _4\"></span>efit are fully recognised in the income statement.6.6 <span class=\"_ _82\"> </span>Fair valueCalculating the fair value of financial and non-financial instruments is a structured process featuring the use of complex evaluation methodologies and techniques that involve collecting up to date information from the reference markets and/or using internal input data.Similar to other estimates, calculating the fair value, albeit based on the best information available and on the adoption on adequate evaluation methodologies and techniques, it intrinsically features random elements and the exercising of professional judgement and could create forecasts with different values from those that will effectively be realised.6.7 <span class=\"_ _82\"> </span>Classification and measurement  of investments made for development<span class=\"_ _4\"></span>  <span class=\"_ _70\"> </span>and maintenance of proprietary  infrastructuresThe Snam Group makes significant investments for development and maintenance of its own infrastructures. Assessing the recoverability of the investments currently underway and the distinction of the costs as improvements, upgrades and transformations that increase the infrastructure and the expenses for ordinary maintenance and repairs which restore but do not increase the performance of the assets, includes valuation elements. These assessments are formulated on the basis of objective criteria that the Group has developed to facilitate an application consistent with its accounting policies.",

The change in the scope of consolidation (548 million euros) refers mainly to the assets recognised in connection with the acquisition: (i) 100% of the share capital of Golar LNG NB 13 Corporation, owner of the FSRU vessel Golar Tundra (327 million euros, net of ancillary acquisition costs); (ii) of 6 and 19 companies engaged in the realisation<span class=\"_ _0\"></span> and management of plants for the promotion of circular economy projects for the energy valorisation of the organic fraction of waste - OFMSW and agricultural waste (158 million euros overall); (iii) of the control of Iniziative Biometano S.p.<span class=\"_ _4\"></span>A. (8 companies consolidated on a line-by-line basis) instead of joint control (37 million euros in total).During the year<span class=\"_ _0\"></span>, Snam capitalised 25 million euros of financial expenses (20 million euros in 2021). Depreciation (747 million euros), included rights-of<span class=\"_ _0\"></span>-use on leased assets, refers to economic and technical depreciation determined on the basis of the useful life of the assets or their remaining possible use by the Company, and, with<span class=\"_ _0\"></span> reference to leased assets, on the basis of the contractual duration if the exercise of any purchase options is not probable. Disposals (30 million euros, net of the related accumulated depreciation and impairment losses) mainly relate to assets in the transportation segment. Write-downs and reversals (126 million euros) mainly relate to assets in the transportation segment (116 million euros<span class=\"_ _0\"></span>) and mainly concern assets not yet available for use and sections of pipelines that are no longer usable.The value of plant and equipment includes the estimated (discounted) costs to be incurred for the removal of facilities and the restoration of sites (498 million euros, net of the provision for amortisation/depreciation) mainly relating to the natural gas storage (411 million euros) and transportation (68 million euros<span class=\"_ _0\"></span>) segments.Other changes (288 million euros) mainly concern: (i) the upward revision of the estimated costs for decommissioning and restoration of sites, basically relating to the storage sector<span class=\"_ _0\"></span>, against the reduction in the expected discount rates (228 million euros in all); (ii) contributions on works for interference with third parties (so-called \"recharges\", 25 million euros).Contractual commitments to purchase property, plant and equipment, and to provide services related to the construction thereof<span class=\"_ _0\"></span>, are reported in Note 26 \u201cGuarantees and commitments\u201d.

The macroeconomic context has been marked over the past 12 months by the presence of a significant inflationary phenomenon to which the major central banks, including the ECB, have responded with significant and repeated increases in their respective key interest rates. The markets in which these phenomena took place (including the Euro<span class=\"_ _0\"></span>zone), show a snapshot of 2022 characterised by 12the presence of widespread signs suggesting the existence of impairment indicators of an exogenous nature. Therefore, as at 31 December 2022, the test was performed for all major CGUs and CGU groupings, in particular: \u2022 <span class=\"_ _29\"> </span>for the sustainable mobility business, consisting of refuelling stations, and micro-liquefaction and bunk<span class=\"_ _0\"></span>ering plants, for 13the Snam4Mobility CGU, with reference to which, as at 31 December 2022, no goodwill remains allocated as a result of the impairment losses carried out; \u2022 <span class=\"_ _29\"> </span>for the A<span class=\"_ _0\"></span>GRI CGU (formerly the IES Biogas CGU) and the WASTE CGU (formerly the Renerwaste CGU), to which goodwill of 21 million euro and 29 million euros, respectively, is allocated. The companies respectively owned by IES Biogas group 14and the Renerwaste group each represent a single CGU (CGU AGRI and C<span class=\"_ _0\"></span>GU WASTE) as the method of managing raw material treatment plants (OFMSW in the case of WASTE plants and, agricultural biomass in the case of AGRI plants<span class=\"_ _0\"></span>) is unitary and centralised. Moreover, in view of the characteristics of such plants, management is not bound by the corporate structure when making decisions on the allocation of resources and investments; \u2022 <span class=\"_ _29\"> </span>for the energy efficiency business, by the grouping of Energy Efficiency CGUs, made up of the TEP Energy Solutions, 15Mieci, Evolve CGUs as well as by the Renovit sub-holding, to which a total goodwill of 19 million euros is allocated; this due to the strong vertical integration between the companies in the management of know-how and technologies, which allows the creation of important synergies in the presentation of a unitary offer to the market. The test was also performed for the Snam Rete Gas, ITG, GNL and Stogit CGUs belonging to the regulated activities of natural gas transportation, regasification and storage; limited to ITG, goodwill of 27 million euros is allocated.16Consistently (i) with the provisions of the agreement signed on 22 December 2022 between Snam Bioenerys group company and Femogas S.p.<span class=\"_ _4\"></span>A. and (ii) in light of the new strategic direction assigned to IES Biogas, which assumes the role of sub-holding company of the Snam group for the AGRI business, increasingly focusing its resources towards the management of proprietary plants aimed at the production of biogas/biomethane from biomass sources of agricultural 17origin, starting from 2022 the AGRI CGU includes, in addition to IES Biogas itself<span class=\"_ _3\"></span>, 24 additional companies. Specifically, these are the 20 companies that were acquired or established by IES Biogas during the year<span class=\"_ _0\"></span>, in addition to a further four companies that were already indirectly controlled by Snam as at 31 December 2022 and will become investee companies of IES Biogas by 2023.Overall, except for the amendments mentioned above, the impairment test was carried out on the basis of a similar CGU set<span class=\"_ _0\"></span>-up to last year<span class=\"_ _0\"></span>.The recoverable amount of the Snam4Mobility CGU was determined, as value in use, based on the cash flows of the corporate plans using the Discounted Cash Flow (DCF) Method. In consideration of the business development and in view of the proposed investment plan, the cash flows were calculated taking into consideration a longer time horizon compared with the forecast 2023-2026 Plan data, in order to be able to consider all the effects that may have a significant impact on these cash flows. The Weighted Average Cost of Capital - W<span class=\"_ _0\"></span>A<span class=\"_ _4\"></span>AC method was used to discount cash flows. The T<span class=\"_ _3\"></span>erminal Value was calculated using the<span class=\"_ _4\"></span> perpetuity method, applying a growth rate substantially in line with market evidence for the expected long-term inflation rate for the reference area, based on the values indicated by the International Monetary Fund ((IMF).With reference to the biogas/biomethane business, the recoverable value of the two CGUs identified, CGU AGRI and C<span class=\"_ _0\"></span>GU WASTE, was determined, as value in use, on the basis of the Discounted Cash Flow (DCF) Method, using the 2023-2026 Plan approved by the Board. For both CGUs, cash flows were calculated taking into consideration a longer time horizon compared to the forecast 2023-2026 Plan data approved by the Board, so as to consider all the effects that could have a significant impact on cash flows. The Weighted Average Cost of Capital - W<span class=\"_ _0\"></span>A<span class=\"_ _4\"></span>AC method was used to discount cash flows.  12 <span class=\"_ _d\"> </span>According to paragraph 12 of IAS 36.13 <span class=\"_ _d\"> </span>As a result of the updated strategic guidelines of the Mobility&amp;Liquefaction Business Unit, as reported in the half-year financial report as of June 30, 2022, in accordance with the provisions of IAS 36 \"Impairment Test,\" instead of the grouping of Mobility CGUs (consisting of Snam 4 Mobility CGU and Cubogas CGU), they were identified as two separate CGUs. As of December 31, 2022, the Cubogas CGU was not included in the scope of C<span class=\"_ _0\"></span>GUs because, as a result of impairments performed during the year<span class=\"_ _0\"></span>, the carrying value of fixed assets pertaining to the CGU was less than 1 million euro.14 <span class=\"_ _d\"> </span>The WASTE CGU in addition to the five companies present as of December 31, 2021, Renerwaste S.r.l., Renerwaste Lodi, Ecoprogetto Milano and Ecoprogetto T<span class=\"_ _0\"></span>ortona and Enersi, it also includes the six companies in the Waste business acquired during 2022: Cupello Renerwaste S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Anzio S.r.l, Biowaste CH4 Foligno S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Group S.r<span class=\"_ _0\"></span>.l., Biowaste CH4 Genova S.r.l., Biowaste CH4 T<span class=\"_ _0\"></span>uscania S.r.l.15 <span class=\"_ _d\"> </span>The difference compared to the 17 million euro present as of December 31, 2021 is due to the goodwill arising from the Esigen business, which was acquired by Mieci during 2022.16 <span class=\"_ _d\"> </span>The agreement, provides that Snam by 2023 will lose control of Iniziative Biometano and certain companies controlled by it, and in the same time frame, provides that IES Biogas will gain direct control of certain companies, now already controlled by the Snam group but directly participated by the same Iniziative Biometano.17 <span class=\"_ _d\"> </span>The 20 companies acquired or incorporated by IES Biogas are 1) Societ\u00e0 Agricola Asola Energie Biogas S.r.l., 2) Societ\u00e0 Agricola T<span class=\"_ _0\"></span>essagli Agroenergie S.r<span class=\"_ _0\"></span>.l., 3) Societ\u00e0 Agricola Santo Stefano S.r.l. 4) Societ\u00e0 Agricola Agrimezzana Biogas S.r<span class=\"_ _0\"></span>.l., 5) Societ\u00e0 Agricola Agrimetano S.r<span class=\"_ _0\"></span>.l.  6) Societ\u00e0 Agricola Carignano Biogas S.r.l.; 7) Emiliana Agroenergia Societ\u00e0 Agricola S.r<span class=\"_ _0\"></span>.l.;  8) Piacentina Agroenergia Societ\u00e0 Agricola S.r<span class=\"_ _0\"></span>.l.; 9) Societ\u00e0 Agricola San Giuseppe Agroenergia S.r.l.; 10) Societ\u00e0 Agricola La V<span class=\"_ _0\"></span>alle Green Energy S.r.l., 11) Societ\u00e0 Agricola Sangiovanni S.r<span class=\"_ _0\"></span>.l.; 12) Societ\u00e0 Agricola G.B.E.

Cash flows were calculated taking into consideration a longer time horizon compared to the forecast 2023-2026 Plan data approved by the Board, so as to consider all the effects that could have a significant impact on cash flows. The Weighted Average Cost<span class=\"_ _0\"></span> of Capital - WAAC method was used to discount cash flows. The Terminal V<span class=\"_ _0\"></span>alue was calculated using the perpetuity method, applying a growth rate in line with market evidence for the expected long-term inflation rate, based on the values indicated by the IMF<span class=\"_ _3\"></span>.With reference to the T<span class=\"_ _0\"></span>ransportation (Snam Rete Gas), Regasification (LNG) and Storage (Stogit) C<span class=\"_ _0\"></span>GUs, the recoverable value was defined as corresponding to the estimate of the value of the Net Invested Capital recognised in these assets for tariff purposes (R<span class=\"_ _4\"></span>AB - Regulatory Asset Base) by the Regulatory Authority for Energy, Networks and the Environment (ARER<span class=\"_ _4\"></span>A), including fixed assets valued using the revalued historical cost method, net working capital<span class=\"_ _0\"></span> flat rate, net of adjustments, including severance indemnities, where applicable, the decommissioning fund and the contributions received. The R<span class=\"_ _4\"></span>AB is also the reference basis for the determination of the service tariffs and, therefore, of the cash flows generated by the activities. With reference to the ITG CGU<span class=\"_ _0\"></span>, the recoverable value of the CGU was calculated as the usage value, based on the Discounted Cash Flow (DCF) Method, using the 2023-2026 Plan approved by the Board. The T<span class=\"_ _0\"></span>erminal Value, consistent with the practice in the energy infrastructure sector<span class=\"_ _0\"></span>, was determined as the disposal value at the end of the plan<span class=\"_ _0\"></span>'s time horizon, assuming the recognition of a premium in line with the market evidence examined as at 31 December 2022. For CGUs where the value in use is determined using the Discounted Cash Flow method, the reference discount rate is the WACC (W<span class=\"_ _0\"></span>eighted Average Cost of Capital - WAC<span class=\"_ _0\"></span>C), corresponding to the weighted average cost of capital, determined, consistently with the reference doctrine and prevailing methodological practices, based on the following main assumptions:\u2022 <span class=\"_ _29\"> </span>Risk F<span class=\"_ _0\"></span>ree Rate: the 10-year sovereign bond, issued by the country of reference, in which the CGU (or group of CGUs) operates is used to determine the risk-free rate;\u2022 <span class=\"_ _29\"> </span>Equity Risk Premium: the equity risk premium is determined by Snam on the basis of the main and authoritative external sources in the sector;\u2022 <span class=\"_ _29\"> </span>Beta Unlevered: calculated as the average figure recorded by the panel of comparable companies identified and specifically selected for each CGU; \u2022 <span class=\"_ _29\"> </span>D<span class=\"_ _3\"></span>/E: the debt-to-equity ratio is determined as an average parameter measured by the panel of comparable companies referring to each CGU;\u2022 <span class=\"_ _29\"> </span>Beta Relevered: it is calculated starting from the Beta Unlevered using the Hamada formula, which tak<span class=\"_ _0\"></span>es into account the tax effect, and the average D/E of the panel of comparable companies considered; \u2022 <span class=\"_ _29\"> </span>Reference Rate for the cost of debt: calculated as the average of the Swap Rate of ten-year instruments denominated in Euro;\u2022 <span class=\"_ _29\"> </span>Credit Spread: determined as an average parameter measured by the panel of comparable companies specifically selected for each CGU. The application of additional risks (Specific Risk Premium) is also envisaged aimed at reflecting, where applicable, within each discount rate, specific considerations referring to the aspects characterising a CGU (or group of CGUs<span class=\"_ _0\"></span>) such as, for example, risks of business or risks associated with the stage of development of the activities performed.Snam's methodology requires these values to be updated annually and, as at 31 December 2022, the WA<span class=\"_ _0\"></span>CCs estimated by the Snam Group and used in the impairment tests were between 5.57% and 8.97%.For all CGUs and CGU groupings, the recoverable value as represented above, was higher than their net book value, including the relevant goodwill, with the exception of the CGU Snam4Mobility<span class=\"_ _0\"></span>. In particular<span class=\"_ _0\"></span>, as at 31 December 2022, the filling station business was affected by: (i) the dynamics of gas prices, which negatively impacted the forecasts for the use of CNG as automotive fuel; (ii) the significant increase recorded in the main parameters (in particular<span class=\"_ _0\"></span>, the risk free rate and the reference rate used to determine the cost of debt) underlying the estimate of the weighted average cost of capital.A comparison between the recoverable amount and the carrying amount of the CGU Snam4Moblity showed a difference in value of 12 million euros, which led to the full write-down of goodwill, amounting to about 7 million euros, as well as of part of the tangible and intangible assets for the remaining amount of about 5 million euros.As required by accounting standard IA<span class=\"_ _4\"></span>S 36, the CGUs subject to impairment testing, whose recoverable value was determined by discounting the expected cash flows deriving from the use of the asset (as well as from its sale at the end of the useful life in some cases), were subjected to a sensitivity analysis of the recoverable amount, in the worst case scenario, which envisages a 0.5 percentage point increase in the discount rate applied during the impairment test. This stress test did not show significantly different results and led, in only one case limited to the WASTE CGU, to an impairment loss of about 5 million euros.",

using the equity method.Disposals and redemptions (86 million euros) refer essentially to the sale of shares of Industrie De Nora S.p.A<span class=\"_ _4\"></span>. for the purpose of listing the company on the stock exchange, a transaction after which Snam holds 25.79% of the share capital (35.63% prior to the IPO), also taking into account capital increases of the same company that were not subscribed.Dividends received (107 million euros) mainly concern the associated companies Italgas (32 million euros<span class=\"_ _0\"></span>), Interconnector Limited (23 million euros), Galaxy (19 million euros<span class=\"_ _0\"></span>) and Senfluga (11 million euros) and the jointly controlled company T<span class=\"_ _0\"></span>er\u00e9ga (15 million euros<span class=\"_ _0\"></span>).The effect of the equity-accounting method recognised in income statement (144 million euros) refers to the share of the net results of companies valued using the equity method, mainly referring to jointly controlled and associated companies (positive results for totally 296 million euros and negative results for totally 152 million euros, of which 148 million euros related to associated company Galaxy Pipeline Assets HoldCo Limited.The effect of the equity-accounting method recognised in the statement of comprehensive income (130 million euros) is mainly attributable to the change in the fair value of hedging derivative financial instruments of the associate T<span class=\"_ _0\"></span>AP and<span class=\"_ _0\"></span> to exchange rate differences (euros/dollars) of the associate Galaxy Pipeline Assets HoldCo Limited.The macroeconomic context has been marked over the past 12 months by the presence of a significant inflationary phenomenon to which the major central banks, including the ECB, have responded with significant and repeated increases in their respective key interest rates. Therefore, as at 31 December 2022, Snam subjected all the main CGUs<span class=\"_ _0\"></span> represented by the equity investments held in jointly controlled companies and associated companies to impairment tests, verifying their recoverability by comparing their book value and their recoverable value, represented by the higher of fair value and value in use. In particular<span class=\"_ _0\"></span>, for carrying out the impairment test, the recoverable value of the equity investments was determined in the configuration of value in use on the basis of the Dividend Discount Model (DDM) or Discounted Cash Flow (DCF) methodology, with the exception of equity in Italgas S.p.A<span class=\"_ _4\"></span>. and Industrie De Nora S.p.<span class=\"_ _4\"></span>A., associated companies, for which the recoverable value was determined on the basis of market quotations at the closing date of the financial year<span class=\"_ _0\"></span>.As of 31 December 2022, the discount rates estimated by the Snam group and used in preparing the impairment tests ranged between 5.75% and 8.24% for CGUs measured using the DDM, and between 4.97% and 8.44% for CGUs<span class=\"_ _0\"></span> measured using the DCF<span class=\"_ _3\"></span>. With reference to the stake held by Snam S.p.A<span class=\"_ _4\"></span>. (84.47%) in T<span class=\"_ _0\"></span>AG, the company owning the pipeline that transports Russian gas to Italy through Austria, passing through Ukraine, Slovakia and up to the T<span class=\"_ _0\"></span>arvisio entr<span class=\"_ _4\"></span>y point, the continuation of the Russia-Ukraine conflict, which began in Februar<span class=\"_ _4\"></span>y 2022, led to a significant reduction in gas flows from Russia in the year recorded at the Baumgarten entry point<span class=\"_ _4\"></span>, equal to about 52.6% compared to 2021, with a consequent reduction in the volumes imported from the T<span class=\"_ _0\"></span>arvisio entr<span class=\"_ _4\"></span>y point (from about 29 billion standard cubic metres in 2021 to about 14 billion standard cubic metres in 2022). In addition, around 85% of the long-term transport capacity contracts expired on 31 December 2022. In a scenario characterised by significant uncertainties about duration and outcome of the conflict, with actions already taken by some states that will lead to the gradual independence of Europe from Russian gas, Snam determined the<span class=\"_ _0\"></span> estimated recoverable amount of the investment based on a multi-scenario approach, attributing a probability of occurrence to each of the scenarios considered. By multiplying the value in use emerging from each of the scenarios considered by the probability of occurrence attributed to them, the recoverable value was thus determined, resulting in a write-down of the equity investment held in T<span class=\"_ _0\"></span>AG of 340 million euros, with a value as at 31.12.2022 of 274 million euros.At the same time, the company is actively cooperating with the competent Austrian authorities on the definition of the regulatory framework applicable from 2025 (regulator<span class=\"_ _4\"></span>y period 2025-2028) in light of the changed context in which the company operates.   With reference to the stake held by Snam S.p.A<span class=\"_ _4\"></span>. (40%) in AS Gasinfrastruktur Beteiligung GmbH, the rise in interest rates, which adversely affected the recoverable value, resulted in a write-down of the investment by 25 million euros, with a value as at 31 December 2022 of 93 million euros. It should be noted that the operating company, GCA<span class=\"_ _4\"></span>, used its interconnection points with Germany during 2022 to ensure the security of supply in Austria and, at the same time, the attainment of the domestic storage filling target. In addition, as of 31 December 2022, the company has long-term transport capacity contracts with gradual expiry dates up to 2031.With reference to Snam's indirect investment, through Snam International B.<span class=\"_ _3\"></span>V<span class=\"_ _3\"></span>. (23.68%), in Interconnector Limited, due to the significant capacity subscriptions that took place in 2022, favoured by the dynamics of gas prices between the UK and the Continent, the company revalued, within the limits of the recoverable value, its investment, written down in previous years for an amount of 31 million euros. The capacity subscriptions made in 2022 also guarantee visibility for the coming years and at least until 2026.       18With the exception of the shareholding in T<span class=\"_ _3\"></span>AP, no collateral is provided.

In particular<span class=\"_ _3\"></span>, purchases were made in implementation of the following Authority Resolutions: (i) Resolution 165/2022/R/Gas, which provided for the procurement by Snam Rete Gas of volumes to cover system gas (about 0.6 billion cubic metres for a total countervalue of 706 million euros as at 31 December 2022); (ii) Resolution 274/2022/R/Gas, which defined the provisions for the filling 22service of last resort (about 1.4 billion cubic metres for a total counter<span class=\"_ _4\"></span>value of 2,348 million euros).The value of the inventories of gas purchased against these resolutions is offset by the recognition, for the same amount, of balance sheet liabilities.The provision for impairment losses essentially relates to the write-down (30 million euros), made in 2014, of 0.4 billion cubic metres of natural gas used in storage activities against strategic gas unduly withdrawn by some service users during 232010 and 2011.Non-current inventories include minimum quantities of natural gas that the storage companies are obliged to hold pursuant to Presidential Decree no. 22 of 31 January 2001 (so-called Compulsor<span class=\"_ _4\"></span>y inventories). The quantities of gas in storage, corresponding to approximately 4.5 billion standard cubic metres of natural gas, are 24determined annually by the Ministry of Economic Development.Inventories are not pledged to guarantee. Inventories do not secure liabilities, nor inventories recognised at net realisation value. 22 <span class=\"_ _d\"> </span>Against the increase in gas inventories, liabilities of equal amounts were recognised, representing the company's obligation to the regulator on the use of gas (Resolution 165/2022/R/gas, 706 million euros) and on the relegation of the amounts obtained from the sale of the relevant quantities of gas (Resolution 274/2022/R/Gas, 2,348 million euros).   23 <span class=\"_ _d\"> </span>For more information regarding the progress of the lawsuits under way, see Note 27.3.2 \u201cRecovering receivables from users of the storage system\u201d. 24 <span class=\"_ _d\"> </span>On 10 January 2022, the Ministr<span class=\"_ _4\"></span>y confirmed the total volume of strategic storage for the contractual year 2022-2023 (01 April 2022 - 31 March 2023) at 4.62 billion cubic metres or approximately 48,846 gigawatt hours GWh, unchanged compared with the thermal year 2021-2022 (01 April 2021-31 March 2022). The Stogit share was unchanged at 4.5 billion cubic metres.  12.1 <span class=\"_ _34\"> </span>Third-party natural gas in storageRisks for third-party assets in storage, amounting to 9,574 million euros(3,653 million euros at 31 December 2021), relate to approximately 7 billion cubic metres of natural gas deposited in storage facilities by customers benefiting from the service. The amount was determined by valuing the quantities of gas stored at the assumed unit repurchase cost<span class=\"_ _4\"></span>, which is approximately 1.32 euros per standard cubic metre (0.54 euros per standard cubic metre at 31 December 2021).",

CHARGESThe provision for decommissioning and site restoration (Euro 498 million) includes the discounted estimate of costs expected to be incurred for the removal of facilities and the restoration of sites essentially in the natural gas storage (411 28million euros) and transportation (68 million euros) segments. The discounting for the provision for decommissioning and site restoration was carried out using the corresponding to the euro area Corporate Bond returns with an \u201c<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>A<span class=\"_ _0\"></span>\u201d rating. The rate thus determined is approximately 3.7%. The last deadline in chronological order for disbursements related to the dismantling and restoration storage sites refers to the Bordolano concession, in 2041. The change in the scope of consolidation (8 million euros) refers to the acquisition of the companies operating in the biomethane business.The other changes (228 million euros) mainly refer to the effects deriving from the increase in the discount rates, mainly referring to the natural gas storage and transportation segment and partially off-set by inflation rates.  Other provisions for risks and charges (44 million euros) mainly concern: (i) charges that the Group<span class=\"_ _0\"></span>\u2019s insurance company Gasrule Insurance DAC expects to incur for insured claims (22 million euros<span class=\"_ _0\"></span>); (ii) the provision for voluntary redundancies (7<span class=\"_ _4\"></span> million euros); (iii) the provision relating to the estimate of probable charges of a fiscal and financial nature (7 million euros<span class=\"_ _0\"></span>). 28 <span class=\"_ _d\"> </span>The costs refer to the estimated expenses for the removal of the connection works to the Livorno LNG regasification terminal - OL<span class=\"_ _32\"></span>T Offshore LNG T<span class=\"_ _0\"></span>oscana. 29The sensitivity of the discount rate represents the

class=\"_ _101\"> </span>27Liabilities for employee benefits, in the amount of 27 million euros, decreased by 9 million euros, mainly due to the increase in expected discount and inflation rates.The provision for employee severance pay (TFR), governed by Article 2120 of the Italian Civil Code, represents the estimated liability determined on the basis of actuarial procedures for the amount to be paid to employees at the time that the employment is terminated. The principal amount of the benefit is equal to the sum of portions of the allocation calculated on compensation items paid during the employment and revalued until the time that such relationship is terminated. Due to the legislative changes introduced from 1 January 2007 for companies with more than 50 employees, a significant part of severance pay to be accrued is classified as a defined-contribution plan since the company\u2019s only obligation is to pay the contributions to the pension funds or to INPS. Liabilities related to severance pay pre-dating 1 January 2007 remain a defined-benefit plan to be valued using actuarial methods. 30FISDE includes the estimated actuarially determined charges for the contributions to be paid to serving and retired managers. 30 <span class=\"_ _d\"> </span>For executives in service, contributions are calculated from the year in which the employee retires and refer to the years of service provided. 31FISDE provides financial supplementary healthcare benefits to Eni Group executives and retired executives whose most recent contract of employment was as an executive with the Eni Group. FISDE is funded through the payment of: (i) contributions by member companies; (ii) contributions paid by Shareholders for themselves and their immediate family; and (iii) ad hoc contributions for specific benefits. The amount of the liability and the healthcare cost are determined on the basis, as an approximation of the estimated healthcare expenses paid by the fund, of the contributions paid by the company in favour of pensioners.The early retirement fund refers to expenses incumbent upon the employer from application of the implementation agreement, relating to the early retirement instrument for employees regulated pursuant to Article 4 paragraphs 1 - 7 of Law 92/2012 (the \u201cFornero Law\u201d).Deferred monetary incentive plans are allocated to executives who have met the goals set out in the year preceding the allocation year<span class=\"_ _0\"></span>, and allocate a basic incentive that is disbursed after three years and varies according to the performance achieved by the Company during the course of the three-year period following the time of the allocation. The benefit is provisioned when Snam\u2019s commitment to the employee arises. The estimate is subject to revision in future periods, based on the final accounting and updates to profit forecasts (above or below target).  The long-term monetary incentive plans, involve the granting and payment<span class=\"_ _4\"></span>, of a variable monetary bonus tied to a measure of company performance. Obtaining the benefit depends on the achievement of certain future performance levels and is conditional on the beneficiary remaining with the Company for the three-year period following the allocation (the \u201cvesting period\u201d).

Exclusively for the EIB loans,<span class=\"_ _0\"></span> the lender has the option to request additional guarantees if Snam\u2019s credit rating is lower than BBB (Standard &amp; P<span class=\"_ _0\"></span>oor\u2019s/Fitch Ratings Limited) or Baa2 (Moody\u2019s) for at least two of the three ratings agencies.The occurrence of one or more of the aforementioned scenarios could have negative effects on Snam Group\u2019s operations, results, balance sheet and cash flow, resulting in additional costs and/or liquidity issues.At 31 December 2022, the financial debt subject to these restrictive clauses amounted to approximately 3 billion.Bonds issued by Snam as at 31 December 2022, with a nominal value of approximately 9.5 billion, referred to securities issued under the Euro Medium T<span class=\"_ _0\"></span>erm Notes programme. The covenants established for the programme<span class=\"_ _0\"></span>\u2019s securities are typical of international market practice and consist of<span class=\"_ _3\"></span>, inter alia, negative pledge and pari passu clauses.

The discounting for the provision for decommissioning and site restoration was carried out using the corresponding to the euro area Corporate Bond returns with an \u201c<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>A<span class=\"_ _0\"></span>\u201d rating. The rate thus determined is approximately 3.7%. The last deadline in chronological order for disbursements related to the dismantling and restoration storage sites refers to the Bordolano concession, in 2041. The change in the scope of consolidation (8 million euros) refers to the acquisition of the companies operating in the biomethane business.The other changes (228 million euros) mainly refer to the effects deriving from the increase in the discount rates, mainly referring to the natural gas storage and transportation segment and partially off-set by inflation rates.  Other provisions for risks and charges (44 million euros) mainly concern: (i) charges that the Group<span class=\"_ _0\"></span>\u2019s insurance company Gasrule Insurance DAC expects to incur for insured claims (22 million euros<span class=\"_ _0\"></span>); (ii) the provision for voluntary redundancies (7<span class=\"_ _4\"></span> million euros); (iii) the provision relating to the estimate of probable charges of a fiscal and financial nature (7 million euros<span class=\"_ _0\"></span>). 28 <span class=\"_ _d\"> </span>The costs refer to the estimated expenses for the removal of the connection works to the Livorno LNG regasification terminal - OL<span class=\"_ _32\"></span>T Offshore LNG T<span class=\"_ _0\"></span>oscana. 29The sensitivity of the discount rate represents the change in the value of the actuarial liability obtained using the end-of-year valuation data, changing the discount rate, without any change in the other assumptions.(million euros<span class=\"_ _0\"></span>)<span class=\"_ _216\"> </span>Change in disc<span class=\"_ _0\"></span>ount rat<span class=\"_ _0\"></span>e10% reduction<span class=\"_ _226\"> </span>10% increaseChange in the provision for decommissioning and sit<span class=\"_ _0\"></span>e restoration at 31.12.2022<span class=\"_ _345\"> </span>30<span class=\"_ _334\"> </span> (28)28  <span class=\"_ _13\"> </span>CRIMINAL<span class=\"_ _0\"></span> <span class=\"_ _0\"></span>AND<span class=\"_ _0\"></span> T<span class=\"_ _32\"></span>AX DISPUTES <span class=\"_ _3\"></span>AND PROCEEDINGS<span class=\"_ _0\"></span> WITH THE<span class=\"_ _0\"></span> REGULA<span class=\"_ _32\"></span>TOR<span class=\"_ _3\"></span>Y <span class=\"_ _0\"></span><span class=\"ls0 ws0\"> </span>AUTHORITY<span class=\"_ _0\"></span> ARERA<span class=\"_ _3\"></span> Snam is involved in civil, administrative and criminal cases and legal actions related to its normal business activities. According to the information currently available and considering the existing risks, Snam believes that these proceedings and actions will not have material adverse effects.The following is a summary of the most significant proceedings; unless indicated other<span class=\"_ _4\"></span>wise, no allocation has been made for the litigation described below because the Company believes it improbable that these proceedings will have an unfavourable outcome or because the amount of the allocation cannot be reliably estimated.At 31 December 2022, risks concerning compensation and disputes related to litigation that is ongoing but where the risk of losing the case is not considered probable amounted to 42 million euros (43 million euros at 31 December 2021).28.1 <span class=\"_ _34\"> </span>Criminal litigationSnam Rete Gas S.p.A. - Event Pineto On 6 March 2015 in Mutignano landslide affected 10 metres of the San Benedetto Del T<span class=\"_ _0\"></span>ronto-Chieti section of the Ravenna-Chieti pipeline, causing it to break with the consequent escape of gas, with a subsequent fire due an electricity pylon collapsing at the same time. With regard to this event, the Public Prosecutor at the Court of T<span class=\"_ _0\"></span>eramo immediately opened an investigation into negligence associated with the forest fire. Upon completion, the Prosecutor requested the Snam Rete Gas technicians and technical managers be brought to court. The committal to trial was ordered by the preliminary hearing judge for 3 October 2018. At the first main hearing on 10 January 2019, the presiding member of the bench asked the defence and the Public Prosecutor to comment on moving the proceedings to a single judge proficient in this issue. The parties referred to the decision of the Court, which after a short period in council chambers, passed the proceedings onto a competent single judge. The first main hearing was held on 17 September 2020, at which all parties presented their requests for evidence. In the past hearings, the examination and cross-examination of the witnesses of the Public Prosecutor\u2019s Office took place, and for the continuation of the activities, the Judge adjourned the hearing to March 2023 for the conclusion of the hearing of the technical consultants of the Public Prosecutor\u2019s Office and for the start of the witness examination of the technical consultants of the defence.28.2 <span class=\"_ _34\"> </span>Proceedings with the <span class=\"_ _0\"></span>Autorit\u00e0  di Regolazione per Energia Reti  e Ambiente <span class=\"_ _4\"></span>- ARERA<span class=\"_ _0\"></span> Snam Rete Gas S.p.A. - Investigation into violations on the subject of natural gas metering with regard to Snam Rete Gas S.p.A<span class=\"_ _0\"></span> and request for information Through Resolution VIS 97/11, notified on 15 November 2011, the ARER<span class=\"_ _4\"></span>A started proceedings to look into whether there were any violations with regard to natural gas metering, relating to alleged irregularities in gas metering with reference to 45 systems owned by the distributor; through Resolution 431/2012/S/Gas the proceedings were brought together with other proceedings involving said events contested by the company launched with regard to the distributor involved. Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. has submitted proposals in relation to the alleged conduct. By means of Resolution 332/2015/S/gas, the ARER<span class=\"_ _4\"></span>A declared the proposals to be inadmissible, on the grounds that they would not be adequate to restore the alignment of interests existing before the alleged violations or to eliminate any immediate and direct consequences of these violations. Upon completion of the investigation on 20 October 2017, the ARER<span class=\"_ _4\"></span>A notified the results to Snam Rete Gas, which confirmed the charges made when the proceedings were initiated. The company has requested time for it to formulate its own defence and, to this end, a hearing was called before the board of the Authority on 1 March 2018 during which the defence brief was submitted. After the proceedings, the Authority, although accepting some of the Company's arguments deemed relevant from the perspective of the quantification of the fine, imposed an administrative monetary fine on Snam Rete Gas, through resolution 206/2018/S/gas of 5 April 2018, of 880 thousand. Though it paid the fine, the Company has appealed Resolution 206/2018/S/gas before the Regional Administrative Court of Milan. As a result of the hearing in June 2022, with ruling 2142/2022 published on 29 September 2022, the Regional Administrative Court upheld Snam Rete Gas's appeal insofar as it complained of the excessive duration of the punitive proceedings. ARER<span class=\"_ _4\"></span>A promptly appealed the ruling before the Council of State.Snam Rete Gas S.p.A. - Resolution 9/2014/S/gas \u2013 \u201cLaunch of punitive proceedings against Snam Rete Gas S.p.A. for non-compliance with Resolution 292/2013/R/gas\u201d  With Resolution 9/2014/S/gas the ARER<span class=\"_ _4\"></span>A launched punitive proceedings against Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. for non-compliance with Resolution 292/2013/R/gas.<span class=\"_ _0\"></span>The proceedings aim to ascertain whether or not delays exist in provisions relating to the enactment of amendments to the Network Code established by Resolution 292/2013/R/gas, with regard to settlement. Upon conclusion of the proceedings, with its resolution 853/2017/S/gas, the Authority sentenced Snam Rete Gas to pay a pecuniary fine of 95 thousand since, although it accepted a part of the Company\u2019s arguments which were significant insofar as determining the amount of the fine, it considered that the Company was late in complying with Resolution 292/2013/R/Gas. Though it paid the fine, the Company has appealed Resolution 853/2017/S/gas before the Regional Administrative Court of Milan. The Regional Administrative Court (T<span class=\"_ _0\"></span>AR), with ruling No. 1914/2022, upheld Snam Rete Gas' appeal. The judgment was not appealed within the time limit and therefore became res judicata.Snam Rete Gas S.p.A. - Resolution 250/2015/R/gas, published on 01 June 2015, concerning: \u201cAdoption of measures on the odorising of gasfor domestic use and similar for end users connecteddirectly to the natural gas transportation networks\u201d Through Resolution 250/2015/R/gas, following the ruling of the Milan regional administrative court, the ARER<span class=\"_ _4\"></span>A amended Article 5 of Resolution 602/2013/R/ gas dealing with the obligation of transportation companies to odorise gas for end users connected directly to the transportation network, which, taking into account the categories of use indicated in the T<span class=\"_ _0\"></span>esto Integrato Settlement Gas (TISG), do not use the gas delivered for merely technological purposes. In this regard, the ARER<span class=\"_ _4\"></span>A ordered that the transportation companies should completed the implementation of the adaptation plans by 31 January 2017, after carr<span class=\"_ _4\"></span>ying out a survey of the redelivery points involved and sending the ARER<span class=\"_ _4\"></span>A the adaptation plan, to be updated every six months, with the description of the technical solution identified. Snam Rete Gas has appealed against the above resolution believing that the deadline for implementing the plan can only be decided after the survey. Having carried out the survey, when sending the plan and the subsequent updates Snam Rete Gas once again found that the deadline set by the ARER<span class=\"_ _4\"></span>A with its Resolution 484/2016/E/gas was unreasonable. Consequently, in the appeal with which Snam Rete Gas challenged Resolution 250/2015/R/gas, it also included an appeal for further grounds against Resolution 484/2016/E/gas asking for the resolutions challenged to be suspended. The request was accepted by the Council of State. Following the hearing that was held on 16 January 2019, through ruling no. 869 of 17 April 2019, the Milan Regional Administrative Court accepted the appeal submitted by Snam Rete Gas declaring the unlawfulness of the deadline set by the Authority because it was clearly unreasonable as it does not take into account the complexity of the activities to be carried out by the transportation company and the need to collaborate with end users on whom the burden of guaranteeing the use of gas in safe conditions for the workers involved weighs.Note that through the Ministerial Decree of 18 May 2018 the Minister for Economic Development placed the responsibility of guaranteeing the use of gas in safe conditions on the end users directly connected to the natural gas transportation network, where there is domestic or similar use of gas, even only in part, if combined with technological uses. Following the functional activities to the implementation of the Decree, the end users demonstrated that they guaranteed the safe use of the gas in accordance with the methods laid down by said Decree.As part of the Consultation Document (DCO 203/2019/R/Gas) as preparation for the revision of the regulation on<span class=\"_ _0\"></span> the transportation service quality, ARER<span class=\"_ _4\"></span>A demonstrated it\u2019s intention to: (i) confirm the regulatory framework pursuant to the above Resolution 250/2015/R/ Gas without setting a deadline by which the Plan has to be implemented; and (ii) promote a regulatory amendment aimed at coordinating the regulation with the aforementioned Ministerial Decree. Following on from what the DCO anticipates, through Resolution<span class=\"_ _0\"></span> 554/2019/R/gas, the Authority confirmed the previous regulatory regime (the obligation of the transportation company to take responsibility for the odorising) thereby<span class=\"_ _0\"></span> putting forward the issue of coordination with the obligations imposed by the Decree. Therefore, pending a possible regulatory change, Snam Rete Gas challenged Resolution 554/2019/R/gas The hearing date remains to be set.28.3 <span class=\"_ _34\"> </span>T<span class=\"_ _32\"></span>ax disputes Snam Rete Gas S.p.A. - IMU/T<span class=\"_ _3\"></span>ASI - Municipalities<span class=\"_ _4\"></span> in Northern ItalySome municipalities of northern Italy sent Snam Rete Gas 17 assessment notices for IMU<span class=\"_ _0\"></span>/<span class=\"_ _4\"></span>T<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>SI for the years 2016, 2017 and 2018, which follow on from requests for information for land registry purposes pursuant to Article 1, paragraph 693 of Law 147/2013. The company has made a provision for risks and charges. Stogit S.p.A. - IMUThe Municipality of Bordolano ascertained the IMU position in relation to the building areas owned by the Company in the territory of the same Municipality for the years 2012 to 2015. The amounts assessed by the Municipality with the notices of assessment relating to the tax years 2012, 2013 and 2014 - as redetermined by the Lombardy Regional T<span class=\"_ _0\"></span>ax Commission - were paid by the Company during 2020, pending the related legal proceedings.The assessment notice issued by the Municipality in 2015 is still sub iudice in first instance.With reference to the subsequent years 2016 - 2017 - 2018, the Company has already adjusted its payments to the higher value assessed by the Municipality.Snam S.p.A. - Questionnaire Q00017/2020 on V<span class=\"_ _3\"></span>A<span class=\"_ _3\"></span>T On 13 February 2020, the Inland Revenue ser<span class=\"_ _4\"></span>ved Snam a V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T questionnaire requesting the reasons for the tax amnesty made in 2016 with reference to the years 2012, 2013, 2014 and 2015. In particular<span class=\"_ _0\"></span>, in 2016, the Company submitted supplementary declarations for the years 2012 to 2014 to acknowledge that, starting in 2012, it was carrying out a new activity of granting loans and that<span class=\"_ _4\"></span>, in relation to this activity, the Company intended to avail itself of the optional separation of activities for V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T purposes pursuant to art. 36, paragraph 3 of Italian Presidential Decree no. 633/1972. As regards 2015, the relevant annual declaration was submitted within the ordinary time limits and an amicable settlement was made to remedy certain irregularities (also related to the keeping of separate accounts) that had affected the correct monthly settlements. Following a preliminary investigation, on 21 December 2020, the Revenue Agency ser<span class=\"_ _4\"></span>ved an order to appear for the establishment of the cross-examination of the years 2012-2013-2014-2015, in order to better verify whether the Company actually behaved \" ex ante\" in this sense.The Company, in order to avoid a long and complex dispute, on 25 March 2021 and 30 November 2022, following the acceptance of the assessment, paid the agreed amounts.28.4 <span class=\"_ _34\"> </span>Other proceedingsSnam Rete Gas S.p.A. - Regulation criteria for natural gas transmission and dispatching tariffs for the period 2010-2013  By ruling No. 2888/2015, the Council of State rejected the appeal filed by ARER<span class=\"_ _4\"></span>A asking it to overturn ruling No. 995/2013 by the Regional Administrative Court of Milan, which voided the provisions of resolutions ARG/gas/184/09, 192/09, 198/09 and 218/10 concerning natural gas transportation and dispatching rates for the 2010-2013 period, specifically with regard to the commodity/capacity allocation, the reform of the entry/exit model and gas for consumption by compression stations (self- consumption<span class=\"_ _0\"></span>).By way of Resolution 428/2015/C/gas, ARERA resolved to appeal for revocation on the grounds of an error of fact against the aforementioned ruling, an appeal which was subsequently withdrawn on 29 March 2018 due to the lack of interest in continuing the proceedings. At the same time, the Authority complied with the aforementioned rulings by way of Resolution 550/2016/R/gas whereby, having reformed the rules on self-consumption, it justified its confirmation of the remaining tariff criteria also in light of the consultations carried out. Given the confirmatory nature of the aforementioned<span class=\"_ _4\"></span> resolution, the original appellant contested for compliance with the aforementioned rulings and a declaration of the nullity of Resolution 550/2016/R/gas. By ruling no. 494/2017,<span class=\"_ _4\"></span> the Milan Regional Administrative Court partially upheld the appeal with specific reference to the issue of the commodity/capacity allocation, finding that the contested Resolution complied inaccurately and partially with ruling No. 995/2013 and that, therefore, the Authority should carr<span class=\"_ _4\"></span>y out an additional assessment of the effects of the choices made. Ruling No. 494/2017 was challenged by the appellant, as well as incidentally by ARER<span class=\"_ _4\"></span>A. In judgement no. 1840/2018 of 23 March 2018, the Council of State, in partial acceptance of the Authority\u2019s cross-appeal, dismissed the action of nullity for breach of judgement filed by the appellant at first instance and ordered the conversion of the proceedings into an ordinary judgement of annulment<span class=\"_ _4\"></span>. The appellant consequently resumed the proceedings before the Milan Regional Administrative Court.It should also be noted that in its recent ruling no. 301/2021, the Milan Regional Administrative Court partially annulled, on partly similar grounds, ARERA Resolution no. 575/2017/R/gas relating to the 2018- 2019 transitional regulatory period. In particular, the caesuras at the 90:10 ratio between the capacity/commodity components were confirmed. In addition, the Regional Administrative Court held that the aforementioned resolution should be annulled in so far as it provides for the determination of unit transport costs on the basis of calculations of gas flows (so-called flows and counter-flows<span class=\"_ _0\"></span>). The judgement was appealed by the Authority. The Regional Administrative Court, in ruling no. 219/2022, upheld a similar appeal in relation to the tariff regime for the 2014-2017 thermal years set forth in ARER<span class=\"_ _4\"></span>A Resolution no. 514/2013/R/gas, in relation to which the terms for any appeal are pending. The ruling, which was appealed by ARERA<span class=\"_ _4\"></span>, was confirmed by ruling No. 8523/2022 of the Council of State.Lastly, it should be noted that the judgements of the Milan Regional Administrative Court (T<span class=\"_ _0\"></span>AR) no. 440/2020 and no. 33/2021 partially annulled the aforementioned Resolution no. 575/2017/R/gas, as well as Resolution no. 114/2019/R/gas (2020-2023 tariff criteria) insofar as they do not provide for a degressive tariff in favour of large gas consumers in implementation of specific primary legislation. Both<span class=\"_ _4\"></span> judgements were appealed by the Authority; the discussion of the appeals before the Council of State was held in April 2022, which was followed by Judgements Nos. 6096/2022 and 6098/2022 rejecting the Authority's respective appeals. In compliance with the aforementioned rulings, ARER<span class=\"_ _4\"></span>A adopted DCO 41/2023/R/gas containing the Authority's guidelines in relation to cost<span class=\"_ _0\"></span>-efficiency measures in the transportation tariff<span class=\"_ _4\"></span> system for subjects with higher natural gas consumption.In all the above cases, the disputed profiles do not affect the revenues recognised to the transport companies.Stogit S.p.A. - <span class=\"_ _0\"></span>Appeals Coordination Environmental Committee (Ricorsi Coordinamento Comitato <span class=\"_ _0\"></span>Ambientalisti) With the Presidential Decree of 16 September 2019, the binding opinion published by the Council of State on 27 June 2019, by which the appeals filed by the Appeals Coordination Environmental Committee plus others were accepted, was implemented. In that Presidential Decree it is stated that: (i) on account of the failure to file the documents relating to the environmental impact assessment in the municipalities of Azzanello and Verolavecchia, the VIA decree issued<span class=\"_ _0\"></span> in 2009 for the construction of the new storage facility at Bordolano is annulled, without prejudice to the provisions contained therein, only in so far as it expresses a favourable opinion on environmental compatibility; (ii) the decree of the Ministry of Economic Development of 28 December 2011 (approval of the change in the work programme of the \"Bordolano Storage\" concession<span class=\"_ _0\"></span>) is annulled, as well as (iii) the measures of the Ministry of the Environment (prot<span class=\"_ _4\"></span>. no. 18804 of 8 August 2013 and prot. no.14583 of 16 May 2014), again on the subject of VIA<span class=\"_ _4\"></span>, without prejudice to the continuing validity of the prescriptions contained therein, to protect public safety and security, which are in no way overturned by the annulment ruling. The Council of State also established the reopening of the VIA procedure and the Ministry of Environment promptly reopened the terms of the VIA (with note DV<span class=\"_ _0\"></span>A U28389 of 29 October 2019) limited to the municipalities of Azzanello and Verolavecchia only; of these, only the municipality of V<span class=\"_ _3\"></span>erolavecchia submitted comments, to which were added those of other parties. The proceedings are currently pending before the T<span class=\"_ _0\"></span>echnical Commission for Environmental Impact Assessment ( Commissione T<span class=\"_ _0\"></span>ecnica per la Valutazione di Impatto<span class=\"_ _0\"></span> Ambientale) and Stogit has provided all the technical clarifications in response to the comments submitted. It should be added that the MED y note U.0025890 of 22 November 2019, issued a measure pursuant to Article 29, paragraph 3 of<span class=\"_ _0\"></span> Legislative Decree no. 152/2006, which allows the continuation of storage activities at the Bordolano plant pending the completion of the VIA. There are grounds to believe that there is a remote risk that the positive environmental impact assessment will not be confirmed; however<span class=\"_ _0\"></span>, also in light of the time that has elapsed, the possibility that the VIA will be confirmed by the Ministry of the Environment with the addition of prescriptive conditions with which Stogit will have to comply can be assessed as probable.Action brought by the Forum <span class=\"_ _0\"></span>Ambientalista and <span class=\"_ _0\"></span>Action brought by WWF Italia - <span class=\"_ _0\"></span>Associazione Salviamo l\u2019Orso marsicano OdV against the integrated environmental authorisation for the new Sulmona power stationOn 2 June 2021, the Environmental Forum - which claims to be an environmental protection association - lodged an appeal with the Regional Administrative Court of Lazio for the annulment of Decree no. 000086 of 11.03.2021 of the Ministry for Ecological Transition concerning the issue of the integrated environmental authorisation (AIA) for the operation of the gas compression station of the company Snam Rete Gas S.p.<span class=\"_ _4\"></span>A. located in Sulmona (AQ) - (ID 7015/9997) as well as all the prior<span class=\"_ _0\"></span>, consequential or in any case related deeds. The applicant claims that its reasons are based on: i) the seismic risk to which the works of Snam Rete Gas are allegedly subject; ii) failure to conduct a preliminary investigation into emissions and failure to take account of their effects on animals and plants in the area concerned; iii) failure to carry out a strategic environmental assessment (SE<span class=\"_ _4\"></span>A) as a precondition for the issue of the AIA; iv) shortcomings in the preliminar<span class=\"_ _4\"></span>y investigation procedure leading to the issue of the AIA. No interlocutor<span class=\"_ _4\"></span>y application was filed; at the hearing at the end of January 2023, the case was retained for decision. In an appeal to the President of the Republic dated 6 August 2021, the Italian Association for the Word Wife Found of Nature (WWF Italia Onlus) and the association Salviamo l'orso Bruno Marsicano_ODV also applied for the annulment of Decree No 0000086 of 11.03.2021 of the Ministry of Ecological Transition, which constitutes the IEA for the new Sulmona power station. The reasons given are: i) the ineffectiveness of the EIA which allegedly failed in 2016; ii) the excess of power in having ignored the observations of the Municipality of Sulmona and of the Maiella National Park, the Abruzzo National Park and the Monte Genzana Alto Gizio Regional Nature Reserve (iii) failure to take adequate account of the seismic risk; (iv) failure to take account of the public\u2019s comments; (v) infringement of the law and misuse of powers on account of failure to carry out preliminar<span class=\"_ _4\"></span>y investigations into atmospheric emissions and the impact on the climate; (vi) infringement of Directive 42/2001 EC by failing to carry out a strategic environmental assessment. Following an objection by Snam Rete Gas, the appeal was resumed before the Lazio Regional Administrative Court by the appellants on 3 November 2021. A hearing on the merits has been set for the end of May 2023.",

The principal amount of the benefit is equal to the sum of portions of the allocation calculated on compensation items paid during the employment and revalued until the time that such relationship is terminated. Due to the legislative changes introduced from 1 January 2007 for companies with more than 50 employees, a significant part of severance pay to be accrued is classified as a defined-contribution plan since the company\u2019s only obligation is to pay the contributions to the pension funds or to INPS. Liabilities related to severance pay pre-dating 1 January 2007 remain a defined-benefit plan to be valued using actuarial methods. 30FISDE includes the estimated actuarially determined charges for the contributions to be paid to serving and retired managers. 30 <span class=\"_ _d\"> </span>For executives in service, contributions are calculated from the year in which the employee retires and refer to the years of service provided. 31FISDE provides financial supplementary healthcare benefits to Eni Group executives and retired executives whose most recent contract of employment was as an executive with the Eni Group. FISDE is funded through the payment of: (i) contributions by member companies; (ii) contributions paid by Shareholders for themselves and their immediate family; and (iii) ad hoc contributions for specific benefits. The amount of the liability and the healthcare cost are determined on the basis, as an approximation of the estimated healthcare expenses paid by the fund, of the contributions paid by the company in favour of pensioners.The early retirement fund refers to expenses incumbent upon the employer from application of the implementation agreement, relating to the early retirement instrument for employees regulated pursuant to Article 4 paragraphs 1 - 7 of Law 92/2012 (the \u201cFornero Law\u201d).Deferred monetary incentive plans are allocated to executives who have met the goals set out in the year preceding the allocation year<span class=\"_ _0\"></span>, and allocate a basic incentive that is disbursed after three years and varies according to the performance achieved by the Company during the course of the three-year period following the time of the allocation. The benefit is provisioned when Snam\u2019s commitment to the employee arises. The estimate is subject to revision in future periods, based on the final accounting and updates to profit forecasts (above or below target).  The long-term monetary incentive plans, involve the granting and payment<span class=\"_ _4\"></span>, of a variable monetary bonus tied to a measure of company performance. Obtaining the benefit depends on the achievement of certain future performance levels and is conditional on the beneficiary remaining with the Company for the three-year period following the allocation (the \u201cvesting period\u201d). This benefit is allocated pro rata over the three-year period depending on the final performance parameters. From 2017, the new share-based variable long-term incentive plan (equity IL<span class=\"_ _1\"></span>T<span class=\"_ _4\"></span>) was introduced instead of the 32long-term monetary incentive plans (IMD and IL<span class=\"_ _32\"></span>T<span class=\"_ _4\"></span>).Seniority bonuses are benefits paid upon reaching a minimum service period at the company and are paid in kind in the form of goods and/or services.The composition and changes in liabilities for employee benefits, determined by applying actuarial methods, are as follows: 31.12.2021<span class=\"_ _32e\"> </span>31.12.2022(million euros<span class=\"_ _0\"></span>)Iso-Other Other TFR<span class=\"_ _48\"> </span>FISDEpension T<span class=\"_ _3\"></span>otal<span class=\"_ _194\"> </span>TFR<span class=\"_ _9\"> </span>FISDET<span class=\"_ _3\"></span>otalliabilitiesliabilitiesFundOPENING LIABILITIES FOR EMPL<span class=\"_ _0\"></span>O<span class=\"_ _0\"></span>YEE 25<span class=\"_ _bd\"> </span>6<span class=\"_ _cb\"> </span>6<span class=\"_ _4d\"> </span>3<span class=\"_ _77\"> </span>40<span class=\"_ _84\"> </span>26<span class=\"_ _bd\"> </span>7<span class=\"_ _4d\"> </span>3<span class=\"_ _77\"> </span>36BENEFITSCosts related t<span class=\"_ _0\"></span>o current services (recognized 1<span class=\"_ _192\"> </span> (4)<span class=\"_ _1b9\"> </span><span class=\"ff63\"> (3)<span class=\"_ _d8\"> </span></span>1<span class=\"_ _1b3\"> </span><span class=\"ff63\">1</span>in \"personnel costs\")Actuarial (gains)/losses resulting from experience adjustments (recognised in other 1<span class=\"_ _2ee\"> </span><span class=\"ff63\">1</span>components in the comprehensiv<span class=\"_ _0\"></span>e income statement)Actuarial (gains) / losses resulting from changes in financial assumptions (recognised 1<span class=\"_ _bd\"> </span>1<span class=\"_ _34e\"> </span><span class=\"ff63\">2<span class=\"_ _207\"> </span></span> (5)<span class=\"_ _c7\"> </span> (3)<span class=\"_ _34f\"> </span><span class=\"ff63\"> (8)</span>in other components in the comprehensiv<span class=\"_ _0\"></span>e income statement)Benefits paid<span class=\"_ _197\"> </span> (2)<span class=\"_ _192\"> </span> (2)<span class=\"_ _34f\"> </span><span class=\"ff63\"> (4)<span class=\"_ _207\"> </span></span> (2)<span class=\"_ _2b3\"> </span><span class=\"ff63\"> (2)</span>CL<span class=\"_ _0\"></span>OSING LIABILITIES 26<span class=\"_ _bd\"> </span>7<span class=\"_ _247\"> </span>3<span class=\"_ _70\"> </span>36<span class=\"_ _298\"> </span>20<span class=\"_ _bd\"> </span>4<span class=\"_ _4d\"> </span>3<span class=\"_ _70\"> </span>27FOR EMPL<span class=\"_ _0\"></span>O<span class=\"_ _0\"></span>YEE BENEFITS31 <span class=\"_ _d\"> </span>The fund provides the same benefits for Snam Group executives.  32 <span class=\"_ _d\"> </span>For more information on the characteristics of this plan, refer to the \u201cOther information\u201d paragraph of the Directors\u2019 Report.

   "value": "27.2 <span class=\"_ _34\"> </span>Risk of changes in interest rates The risk of changes in interest rates is associated with fluctuations in interest rates affecting the market value of the Company\u2019s financial assets and liabilities and its net financial expense. Snam\u2019s objective is to optimize the interest rate risk while pursuing its financial objectives. Snam Group has adopted a centralised organisational model. In accordance with this model, Snam\u2019s various departments access the financial markets and use funds to cover financial requirements, in compliance with approved objectives, ensuring that the risk profile stays within defined limits. At 31 December 2022, the Snam Group used external financial resources in the form of bond loans and bilateral and syndicated loans with banks and other financial institutions, in the form of medium- to long-term loans and bank credit lines at interest rates indexed to the reference market rates, in particular the E<span class=\"_ _0\"></span>urope Interbank Offered Rate (Euribor), and at fixed rates. The exposure to the risk of changes in interest rates at 31 December 2022, taking into account the hedging transactions put in place, was approximately 20% of the total exposure of the Group (28% at 31 December 2021). At 31 December 2022, Snam had interest rate swap (IRS) derivative contracts in place for a notional total of 106 million euros, relating to hedges on a 106 million euros floating-rate bond maturing in 2024. Though the Snam Group has an active risk management policy, the rise in interest rates relating to floating-rate debt not hedged against interest rate risk could have negative effects on Snam Group\u2019s operations, equity situation and financial position. E<span class=\"_ _0\"></span>ven considering the limited exposure to changes in interest rates, limited to 20% of the Group\u2019s total exposure and fully attributable to the Euribor rate, a possible change in the method of calculating the latter and the related fall-back clauses that may be formulated could result in the Snam Group having to adjust the financial contracts that may be affected by the aforementioned change and/or the management of prospective cash flows.The effects on shareholders\u2019 equity and net profit at 31 December 2022 are shown below, assuming a h<span class=\"_ _0\"></span>ypothetical change in the interest rate basis points of +/-10% actually applied during the course of the year:31.12.2022Other components Income st<span class=\"_ _0\"></span>atement in the compr<span class=\"_ _0\"></span>ehensive (million euros<span class=\"_ _0\"></span>)resultincome st<span class=\"_ _0\"></span>atementInterest  Interest   Interest  Interest   +10 bps-10 bps+10 bps-10 bpsInterest rate change effect<span class=\"_ _1e0\"> </span><span class=\"ls0\"> (3)<span class=\"_ _52\"> </span>3<span class=\"_ _b0\"> </span> <span class=\"_ _167\"> </span> </span>Impacts gross of tax effect<span class=\"_ _35d\"> </span> (3)<span class=\"_ _52\"> </span>3T<span class=\"_ _0\"></span>ax effect<span class=\"_ _178\"> </span>1<span class=\"_ _235\"> </span> (1)IMP<span class=\"_ _0\"></span>ACTS NET OF T<span class=\"_ _3\"></span>A<span class=\"_ _4\"></span>X EFFECT<span class=\"_ _16c\"> </span> (2)<span class=\"_ _52\"> </span>2(*)  The change in the interest rate impacts on the change of fair value of derivative hedging instruments rec<span class=\"_ _0\"></span>ognised amongst other components in the comprehensive inc<span class=\"_ _0\"></span>ome statement and, therefore, does not impact on the income statement result.",

Default on or delayed payment of fees may have a negative impact on Snam's economic results and financial balance. For the risk of non-compliance by the counterparty concerning contracts of a commercial nature, the credit management for credit recovery and any disputes are handled by the business units and the centralised Snam departments. For trade receivables, provisions for bad debts reflect the value of expected losses over the life of the receivable and are made on the basis of the expected credit loss model or specifically on credit positions that present special risk elements. For further details, please refer to Note 5 \"Significant Accounting Policies - Financial assets measured at amortized cost\".Snam, as far as regulated activities are concerned, which currently represent almost all activities, provides its business services to 230 operators in the gas sector, with 10 operators representing appro<span class=\"_ _0\"></span>ximately 67% of the entire market (Eni, Edison and Enel Global T<span class=\"_ _0\"></span>rading hold the top three spots). The rules for Costumer access to the services offered are established by the Authorities and set out in the Network Codes.For each type of service, these documents explain the rules regulating the rights and obligations of the parties involved in selling and providing said services and contain contractual conditions, which significantly reduce the risk of customer default. The Codes contain guarantees to be provided to cover the obligations undertaken. In certain cases, if the customer has a credit rating issued by leading international organisation, the issuing of these guarantees can be mitigated. The regulations also contain specific clauses which guarantee the neutrality of the entity in charge of balancing, an activity carried out from 1 December 2011 by Snam Rete Gas as the major transportation company. In particular<span class=\"_ _3\"></span>, the current balancing rules require that Snam, on the basis of financial merit criteria, mainly, operates in buying and selling on the GME balancing platform to guarantee the necessary resources for the safe and efficient movement of gas from the injection points to the withdrawal points in order to guarantee the constant equilibrium of the network.  As regards non-regulated activities, which will become increasingly important over the Plan time horizon, the Company, through its centralised functions, performs a prior analysis of the financial soundness of counterparties in order to minimise this risk.Snam\u2019s maximum exposure to credit risk as at 31 December 2022 is represented by the book value of the financial assets recorded in the financial statements, detailed in Note 15 \u201cTrade and other receivables\u201d.The following table shows a breakdown of trade and other receivables by maturity, indicating the gross value and the value net of the provision for impairment losses:31.12.2021<span class=\"_ _136\"> </span>31.12.2022(million euros<span class=\"_ _0\"></span>)T<span class=\"_ _3\"></span>rade Other T<span class=\"_ _3\"></span>rade Other (*)(*)rec<span class=\"_ _0\"></span>eivables rec<span class=\"_ _0\"></span>eivables T<span class=\"_ _3\"></span>otalT<span class=\"_ _3\"></span>otalrec<span class=\"_ _0\"></span>eivables rec<span class=\"_ _0\"></span>eivables Non-overdue receivables<span class=\"_ _159\"> </span>2,412<span class=\"_ _14d\"> </span>602<span class=\"_ _5e\"> </span>3,014<span class=\"_ _51\"> </span>3,686<span class=\"_ _160\"> </span>380<span class=\"_ _62\"> </span>4,066Overdue receivables:<span class=\"_ _6f\"> </span>317<span class=\"_ _185\"> </span>317<span class=\"_ _169\"> </span>558<span class=\"_ _185\"> </span>558   - from 0 to 3 months<span class=\"_ _10e\"> </span>116<span class=\"_ _185\"> </span><span class=\"ff6b\">116<span class=\"_ _169\"> </span></span>345<span class=\"_ _185\"> </span><span class=\"ff6b\">345</span>   - from 3 to 6 months<span class=\"_ _b4\"> </span>54<span class=\"_ _1e6\"> </span><span class=\"ff6b\">54<span class=\"_ _16d\"> </span></span>60<span class=\"_ _1e6\"> </span><span class=\"ff6b\">60</span>   - from 6 to 12 months<span class=\"_ _b4\"> </span>8<span class=\"_ _1f5\"> </span><span class=\"ff6b\">8<span class=\"_ _16d\"> </span></span>23<span class=\"_ _1e6\"> </span><span class=\"ff6b\">23</span>   - beyond 12 months<span class=\"_ _ce\"> </span>139<span class=\"_ _185\"> </span><span class=\"ff6b\">139<span class=\"_ _169\"> </span></span>130<span class=\"_ _185\"> </span><span class=\"ff6b\">130</span>T<span class=\"_ _0\"></span>otal trade receivables and other 2,729<span class=\"_ _160\"> </span>602<span class=\"_ _62\"> </span>3,331<span class=\"_ _51\"> </span>4,244<span class=\"_ _160\"> </span>380<span class=\"_ _62\"> </span>4,624receivables(*)   The values are shown net of provision for bad debt of an amount equal t<span class=\"_ _0\"></span>o 100 million euros (85 million at 31 December 2021).The net book value of trade receivables past due at 31 December 2022 and not written down, amounting to 558 million euros, mainly refers to trade receivables of companies operating in regulated businesses; in particular they refer to: (i) the transportation segment (442 million euros), mainly for receivables from users related to balancing and settlement service items. These receivables fall within the neutrality mechanisms envisaged by the current regulatory framework; (ii) to the storage segment (77 million euros), in particular V<span class=\"_ _3\"></span>A<span class=\"_ _0\"></span>T invoiced to users for the use of strategic gas unduly withdrawn and not replenished by them within the terms established by the Storage Code during 2010 and 2011. As provided for under the applicable legislation, notices of V<span class=\"_ _0\"></span>A<span class=\"_ _3\"></span>T changes may be issued at the end of bankruptcy proceedings and unsuccessful enforcement proceedings.The following is a description of the credit recovery activities carried out against certain users of the transportation and balancing system and the storage system.2<span class=\"_ _0\"></span>7<span class=\"_ _0\"></span>.<span class=\"_ _3\"></span>3.<span class=\"_ _3\"></span>1 <span class=\"_ _33\"> </span>Recovering receivables from certain users of the transportation and balancing system   The balancing service ensures that the network is safe and that costs are correctly allocated between the market operators. Balancing has both a physical and a commercial purpose. The physical balancing of the system consists of the<span class=\"_ _0\"></span> set of operations through which the Dispatching department of Snam Rete Gas controls flow parameters (capacity and pressure) in real time in order to ensure that gas can move safely and efficiently from injection points to withdrawal points at all times. Commercial balancing consists of the activities required to correctly schedule, account for and allocate the transported gas, as well as the fee system that encourages users to maintain a balance between the volumes they inject into and withdraw from the network. Pursuant to the balancing regime, which was introduced by Resolution ARG/gas 45/11 and came into effect on 1 December 2011, in its role as Balancing Supervisor, Snam Rete Gas must ensure that it procures the quantities of gas<span class=\"_ _0\"></span> required to balance the system and offered on the market by users through a dedicated platform of the Gestore dei Mercati Energetici (GME), and, accordingly<span class=\"_ _0\"></span>, it must financially settle the imbalances of individual users by buying and selling gas on the basis of a benchmark unit price (the \u201cprinciple of economic merit\u201d). The Company must also ensure that it recovers sums owed for the settlement of imbalances from any defaulting users. <span class=\"ls0\"> </span>Unpaid receivables relating to the period from 1 December 201<span class=\"_ _3\"></span>1 to 23 October 2012The initial regulation laid down by the Authority with Resolution ARG/gas 155/11 stated that Users had to provide specific guarantees to cover their exposure and, where Snam Rete Gas had performed its duties diligently and had not been able to recover the costs related to provision of the service, these costs would have been recovered through a special fee determined by the Authority.36With a subsequent resolution 351/2012/R/ gas, the Authority provided for the application of the CVBL variable unit fee to cover uncollected receivables, arranging for the charges to be recovered to be spread over a minimum of 36 months with a maximum monthly amount of 6 million euros.The Authority subsequently launched a fact<span class=\"_ _0\"></span>-finding investigation into the way in which the balancing service was provided for<span class=\"_ _4\"></span> 37the period between 1 December 2011 and 23 October 2012. The investigation was closed by Resolution 144/2013/E/gas of 5 April 2013. On the same date, the Authority: (i) opened proceedings to determine the share of costs arising from uncollected receivables owing to the gas balancing supervisor for the period 1 December 2011 - 23 October 2012; and (ii) opened six<span class=\"_ _4\"></span> proceedings aimed at establishing whether there have been violations regarding the natural gas balancing service.<span class=\"_ _4\"></span> With regard to the preliminary investigation discussed in point (i) above, the proceedings were closed by means of Resolution 608/2015/R/gas, with which the Authority decided not to pay a share of the uncollected receivables in relation to specific cases analysed in the preliminary investigation, in any case subject to Snam Rete Gas\u2019s right to withhold the receivables relating to the income statement entries on balancing, possibly already recuperated. The Company appealed Resolution 608/2015/R/gas, before the Regional Administrative Court of Milan, which partially admitted the appeal submitted by the Company with ruling 942/2017; this was in turn partially appealed by the Company and the Authority. The judgement was then confirmed by Council of State judgement no. 1630/2020.During the above-mentioned investigation period, Snam Rete Gas, having terminated the transportation contracts of the six users involved in the aforementioned proceedings since they either defaulted on payments or failed to comply with the balancing obligations set forth in the industry regulations and the Network Code, initiated steps to recover the receivables relating to balancing and transport items.The competent legal authorities have issued eleven provisionally enforceable injunction orders, six of which relate to receivables 38related to the balancing service and five to receivables for the transportation ser<span class=\"_ _4\"></span>vice, for which Snam Rete Gas has initiated enforcement procedures that have led to the recovery of negligible amounts with respect to the overall debt position of the<span class=\"_ _4\"></span> Users, also in consideration of the bankruptcy procedures initiated in the meantime by all the users in question.36 <span class=\"_ _d\"> </span>The aforementioned resolution was annulled pursuant to the ruling 1587/2014 of the Regional Administrative Court of Milan insofar as the obligation of Users to pay the CVBL consideration of 0.001 \u20ac/Scm with effect from 1 October 2012. Moreover, with the subsequent Resolution 372/2014/R/gas the coefficient was redefined at the same amount of 0.001 \u20ac/Scm.37 <span class=\"_ _d\"> </span>The time period set for the preliminary investigation which was initially limited to 1 December 2011 - 31 May 2012, was subsequently extended to 23 October 2012.38 <span class=\"_ _d\"> </span>The users in question have appealed against some of these injunctions. Specifically, as well as requesting the suspension of the provisional enforceability and the revocation and/or declaration as null and void of the injunctions themselves, three users have submitted counterclaims requesting that Snam Rete Gas be ordered to compensate them for alleged damage suffered. The oppositions were declared null and void, with the resulting lapse of the demand and the passage into judgement of the injunction decrees.In particular<span class=\"_ _0\"></span>, at present:\u2022 <span class=\"_ _29\"> </span>five Users were declared bankrupt. With regard to all five Users, Snam Rete Gas obtained measures for admission to the list of creditors for the receivable owed, plus interest. As part of these proceedings, a proposal for arrangement with creditors was submitted and approved by the majority of the creditors; the bankruptcy proceedings, following the final distribution, were closed. A second procedure was also closed after approval and execution of the final distribution; \u2022 <span class=\"_ _29\"> </span>a User applied for admission to the arrangement procedure and the Judicial Authority issued the approval 39of the arrangement.  Unpaid receivables after 23 October 2012In 2013, two further transportation contracts were terminated and Snam Rete Gas initiated injunction proceedings.It obtained three payment orders, of which two for receivables relating to the balancing service and one<span class=\"_ _4\"></span> for the transportation service. Both Users appealed, with<span class=\"_ _4\"></span> the relative rulings rejecting the claims and consolidating the securities acquired by Snam Rete Gas. The executive procedures that were initiated resulted in a negligible recovery of amounts when compared to the overall<span class=\"_ _4\"></span> amounts due from the Users which were then declared bankrupt. Snam Rete Gas regularly submitted its claims in the respective arrangements with creditors. The insolvency proceedings both ended with the recovery of minimal<span class=\"_ _4\"></span> amounts with respect to the bankrupt company's overall debt.In 2014, a further transport contract was terminated and Snam Rete Gas initiated provisional executive procedures for recovery of the receivables, one relating to balancing<span class=\"_ _4\"></span> services and the other to transportation ser<span class=\"_ _4\"></span>vices. The User was declared bankrupt and Snam Rete Gas was admitted to the current list of creditors for the entire debt due, plus interest. Finally, in 2015 a further transportation contract was terminated and Snam Rete Gas initiated debt recovery<span class=\"_ _4\"></span> measures, securing two provisional executive injunctions against the User<span class=\"_ _0\"></span>, one for the balancing service and the other for the transport service. The User was subsequently<span class=\"_ _4\"></span> declared bankrupt and Snam Rete Gas has regularly submitted its claims for the arrangements with creditors. Given the insolvency of the bankrupt, the bankruptc<span class=\"_ _4\"></span>y proceedings ended without recovery of any sums. Snam Rete Gas, as stated in the provisional executive injunctions issued by the Court, has engaged in proper conduct and complied with the provisions of the transportation contract, the Network Code and, more generally, the applicable legislation.39 <span class=\"_ _d\"> </span>In respect of the approval provision, a claim was brought before the Court of Appeal of Turin, and \u2013 in respect to the confirmation procedure adopted by the same Court \u2013 the appeal was brought before the Court of Cassation, which subsequently rejected the appeal.Lastly, we note that on 12 February 2016 the Public Prosecutor at the Court of Milan ordered the urgent preventive seizure of the moveable and fixed assets belonging to companies and attributable in various guises to the above-mentioned five Users. In May 2017, the investigation was concluded and the investigated parties were charged with the being involved in a criminal association and committing aggravated fraud against Snam Rete Gas. At the preliminary hearing set for 19 December<span class=\"_ _4\"></span> 2018, the Judge accepted Snam Rete Gas joining the proceedings as a civil party. The Court granted the pre-trial requests and declared the trial open. Following the conclusion of the preliminary hearing, the<span class=\"_ _4\"></span> Court on 15 February 2023 recognized the criminal liability of the defendants, condemning them, inter alia, to pay compensation for damages in favor of Snam Rete Gas. We are awaiting the filing of the reasons for the sentence, which is set within 90 days. These criminal proceedings resulted in the formal complaint report (and subsequent supplementary reports) filed by Snam Rete Gas, as offended party, in October 2012 for the crimes of falsehood and aggravated fraud. 27.3.2 <span class=\"_ _29\"> </span>Recovering receivables from users<span class=\"_ _4\"></span> <span class=\"_ _0\"></span><span class=\"ls0\"> </span>of the storage system<span class=\"_ _4\"></span> Withdrawals made from strategic storage by three users, invoiced by Stogit and not replenished by the user under the terms specified by the Storage CodeFollowing withdrawals from strategic storage made by a User in November and December 2010, Stogit asked for and obtained an injunction with regard to the sums due that the user failed to pay.<span class=\"_ _3\"></span>The provisional enforceability was confirmed during the opposition launched by the opposing party. The appropriate executive actions were launched as a result.Following the withdrawals and the failure to replenish the strategic gas in the initial months of 2011 as well, Stogit requested and obtained a second provisional executive injunction for the further sums accrued.Urgent proceedings were also launched for the replenishment of all the gas unlawfully withdrawn, concluding with the conviction of the debtor<span class=\"_ _0\"></span>, with the subsequent application for injunctive relief also being rejected. In 2012 the above user together with another two users (who also defaulted with regard to Stogit) were added to the proceedings for an arrangement with creditors, in which Stogit formally transmitted and documented the amounts of its receivables with these users.Moreover<span class=\"_ _0\"></span>, following the sub-proceedings to dismiss<span class=\"_ _0\"></span> the arrangement, the Court of Asti declared two of the above-mentioned users bankrupt. In both cases, Stogit promptly filed a proof of claim and its receivables were admitted in full.However<span class=\"_ _0\"></span>, the procedure for an arrangement with<span class=\"_ _0\"></span> creditors is continuing with regard to the third user<span class=\"_ _0\"></span>,<span class=\"_ _0\"></span> which was appealed by one of the creditors.

   "value": "27.4 <span class=\"_ _34\"> </span>Liquidity risk Liquidity risk is the risk that new financial resources may<span class=\"_ _0\"></span> not be available (funding liquidity risk) or that the Company may be unable to convert assets into cash on the market (asset liquidity risk), meaning that it cannot meet its payment commitments.<span class=\"_ _3\"></span>This may affect profit or loss should the Company be obliged to incur extra costs to meet its commitments or<span class=\"_ _0\"></span>, in extreme cases, lead to insolvency and threaten the Company\u2019s future as a going concern.Under the financial plan, Snam\u2019s risk management system aims to establish a financial structure that, in line with the business objectives, ensures sufficient liquidity for the Group, minimising the relative opportunity cost and maintaining a balance in terms of the duration and composition of the debt.The financial market is characterised by a continuous growth of sources of financing for companies able to improve the environmental impact of their investments. The interest of the investors is linked and subordinated to the ability of the companies themselves to achieve certain objectives in terms of environmental sustainability.  With a view to the correct management of liquidity risk, the diversification of funding sources also through the use of sustainable finance instruments is therefore crucial to guarantee companies wide access to financial markets at competitive costs, with consequent positive effects on the economic situation, equity and financial position of the companies themselves. Similarly, for Snam, the failure to achieve certain KPIs in the ESG area, within the general objective of the Group to make its business more sustainable in the medium-long term, could lead to higher financing costs or to the lack of access to some sources of funding.Mitigation of this risk is based on Snam's extreme attention to ESG issues, traditionally a significant and structured part of the company's strategy.<span class=\"_ _0\"></span> Consistent with this approach, during 2018 Snam finalised the transformation of its 3.2 billion euros syndicated credit lines into sustainable loans, constituting at the time the third largest sustainable loan signed in the world and the first by a gas utility. This loan provides for bonus/ malus mechanisms based on the achievement of certain KPIs in the ESG (Environment, Social, Governance) area. In addition, Snam issued (i) in February 2019, its first 500 million euros Climate Action Bond, (ii) between 2020 and 2021 T<span class=\"_ _0\"></span>ransition Bonds for 2,350 million euros (iii) in January 2022, the inaugural dual-tranches Sustainability-linked Bond (SLB<span class=\"_ _0\"></span>) for 1.5 billion euros, whose economic performance is linked to the achievement of certain sustainability targets, and (iv) in November 2022 the inaugural EU T<span class=\"_ _0\"></span>axonomy-Aligned T<span class=\"_ _0\"></span>ransition Bond for 300 million euros. These are aimed at financing investments in environmental sustainability and energy transition, while for SLB instruments the return is linked to the achievement of methane and CO emission reduction targets. It should 2be noted that the January 2022 issue was associated with a Liability Management exercise that led to the repurchase of 350 million euros of bonds to proactively manage future debt maturities and accelerate the transition from plain vanilla bonds to sustainable finance instruments. In 2022, Snam finalised with major relationship banks (i) Revolving Credit F<span class=\"_ _0\"></span>acilities (RCF) for a total of 1.2 billion euros, of which 1.1 billion euros in KPI-linked format (ii) bank loans for 375 million euros, of which 275 million euros in Green loan and KPI-linked format and (iii) a bank loan agreement for 1.5 billion euros with a maximum term of 24 months. During 2020, Snam also renewed its Euro Commercial Paper programme, increased from 2 to 2.5 billion euros, linking it to environmental and social sustainability objectives in line with the sustainable loan and obtaining an ESG rating for the instrument equal to EE assigned by the ESG rating company Standard Ethics, confirmed in 2021 and increased to EE+ in 2022. Finally, in June 2021, Snam signed a loan agreement with the European Investment Bank (EIB) for a total of 150 million euros to support the group's energy efficiency projects in the residential and industrial sectors. Specifically, the agreement concerns initiatives totalling 200 million euros planned by the subsidiary TEP Energy Solutions, which consist mainly in the energy upgrading of residential buildings and the implementation of energy efficiency and decarbonisation measures for industrial activities, including the installation of photovoltaic panels. The loan is characterised by a framework loan structure, which can be used in several tranches within a period of three years; each tranche will have a maximum total duration of 15 years. As at 31 December 2022, this line was utilised for approximately 110 million euros. As shown in section 27.2 \u201cRisk of changes in interest rates\u201d, the Company had access to a wide range of funding sources through the credit system and the capital markets (bilateral contracts, pool financing with major domestic and international banks, loan contracts with the European Investment Bank (EIB), bond loans and Commercial Papers<span class=\"_ _0\"></span>).Snam\u2019s objective is to maintain a debt structure that is balanced in composition between bond loans and bank credit, and the availability of usable committed bank credit lines, in line with its business profile and the regulatory environment in which Snam operates.At 31 December 2022, Snam had unused committed long-term credit lines for an amount of around 5.9 billion euros, of which (i) syndicated credit lines of 4.65 billion euros (ii) Revolving Credit F<span class=\"_ _0\"></span>acilities (RCF) for a total of 1.2 billion euros (iii) approximately 40 million euros relating to the framework loan signed with the EIB in June 2021. At 31 December 2022, Snam has a Euro Medium T<span class=\"_ _0\"></span>erm Notes (EMTN) programme in place for a maximum total nominal value of 13 billion, used for approximately 9.5 billion euros and a Euro Commercial Paper Programme (E<span class=\"_ _0\"></span>CP) for a maximum total nominal value of 2.5 billion euros, used at 31 December for 1,130 million euros.Snam\u2019s cash and cash equivalents mainly refer to current accounts and bank deposits readily collectable.The Group\u2019s main long-term financial payables include covenants that are typical of international practice, such as negative pledge and pari passu clauses. F<span class=\"_ _0\"></span>ailure to meet these clauses, and the occurrence of other events, for example cross-default events, may result in Snam\u2019s failure to comply and could trigger the early repayment of the relative loan, resulting in additional costs and/or liquidity issues. There are no covenants among commitments that involve compliance with ratios of an economic and/or financial nature. Among the factors that define the risk perceived by the market, creditworthiness, assigned to Snam by rating agencies, plays a decisive role because it influences their ability to access sources of financing and the related economic conditions. A worsening of this creditworthiness could therefore constitute a limitation on access to the capital market and/or an increase in the cost of sources of financing, with consequent negative effects on the Group\u2019s economic situation, equity and financial position.Snam\u2019s long term rating is: (i) Baa2 with negative outlook, confirmed on 06 September 2022 by Moody's Investor Services; (ii) BBB+ with stable outlook, confirmed on 06 February 2023 by Standard &amp; Poor's Global Rating (\u201cS&amp;P\u201d); (iii) BBB+ with stable outlook, confirmed on 16 February 2023 by Fitch Ratings (\u201cFitch\u201d). Snam\u2019s long-term rating by Moody\u2019s, Fitch and Standard &amp; Poor\u2019s is a notch higher than that of Italian sovereign debt. Based on the methodology adopted by Moody's and S&amp;P<span class=\"_ _3\"></span>, the downgrade of one notch from the current rating of the Republic of Italy would lead to a corresponding reduction of Snam\u2019s current rating. In this regard, it should be noted that on 30 September 2022, Moody's confirmed the rating of the Italian Republic, maintaining the negative outlook, which had already been lowered on 5 August 2022; this action had caused Snam's Outlook to be revised to negative on 9 August 2022. On 26 July 2022, S&amp;P revised the Italian Republic's Outlook from positive to stable, with corresponding action on Snam's Outlook on 29 July 2022. The next reviews of the Rating Agencies for the Italian Republic are scheduled for 21 April 2023 for S&amp;P<span class=\"_ _3\"></span>, 12 May 2023 for Fitch, 19 May 2023 for Moody's.The company\u2019s short-term rating, used as part of Snam<span class=\"_ _0\"></span>\u2019s Commercial Paper programme, is P-2 for Moody\u2019s, A-2 for S&amp;P and F2 for Fitch.Although the Snam Group has relations with diverse counterparties with a high credit standing, based on the management policy and ongoing monitoring of their credit risk, the default of a counterparty or the difficulty to liquidate assets on the market could have negative effects on Snam Group\u2019s operations, equity situation and financial position.The table below shows the repayment plan contractually established in relation to the financial payables, including interest payments and other liabilities connected to derivative instruments:Contractual c<span class=\"_ _0\"></span>ash \ue7aeowsBook value as (million euros<span class=\"_ _0\"></span>)T<span class=\"_ _3\"></span>otal \ue7aeows<span class=\"_ _207\"> </span><span class=\"ff68\">2022<span class=\"_ _8c\"> </span>2023<span class=\"_ _8c\"> </span>2024<span class=\"_ _8c\"> </span>2025<span class=\"_ _8c\"> </span>2026<span class=\"_ _12\"> </span><span class=\"ls2b ws2d\">Beyond</span></span>at 31.12.2021Bank loans<span class=\"_ _23e\"> </span>3,695<span class=\"_ _a6\"> </span>3,695<span class=\"_ _2a8\"> </span><span class=\"ff6a\">1,297<span class=\"_ _344\"> </span>457<span class=\"_ _45\"> </span>719<span class=\"_ _344\"> </span>121<span class=\"_ _344\"> </span>120<span class=\"_ _45\"> </span>981</span>Bond loans (*)<span class=\"_ _22d\"> </span>9,138<span class=\"_ _a6\"> </span>9,139<span class=\"_ _2ba\"> </span><span class=\"ff6a\">1,130<span class=\"_ _344\"> </span>879<span class=\"_ _2ba\"> </span>1,191<span class=\"_ _2ba\"> </span>1,339<span class=\"_ _2a8\"> </span>1,250<span class=\"_ _2ba\"> </span>3,350</span>Euro C<span class=\"_ _0\"></span>ommercial Paper -

In 2022, the free allocation for the Snam Group was 154,657 allowances, an increase of 9.8 % compared to 2021, due to the new rules introduced by the aforementioned legislation for the fourth ETS period. In FY 2022, dioxide carbon emissions of Snam Group facilities covered by the ETS were overall greater than the emission allowances allocated. Compared to approximately 0.93 million tonnes of carbon dioxide emitted into the atmosphere, a deficit has therefore been recorded of approximately 0.77 million tonnes. The deficit was offset by the quotas purchased by the various companies, with an approximately cost of 57.4 million euros recognised in \u201cOther operating costs and expenses\u201d. There are no costs for Renovit (TEP), because the purchase of CO quotas is borne by the company to which the 2plant supplies energy net of the quotas in the hands of Renovit (TEP) for feeding electricity into the grid. These amounted to about 4,300 units, with a countervalue of about 0.3 million euros.The increase in purchased CO allowances is due to the increase in emissions resulting from the increase in gas 2consumption due to the increase in regasified, stored gas and to transport more natural gas from the South to the North of Italy.The increase in the number of CO allowances purchased and the increase in purchase prices led to higher costs than in the 2previous year<span class=\"_ _0\"></span>.",

In 2022, the free allocation for the Snam Group was 154,657 allowances, an increase of 9.8 % compared to 2021, due to the new rules introduced by the aforementioned legislation for the fourth ETS period. In FY 2022, dioxide carbon emissions of Snam Group facilities covered by the ETS were overall greater than the emission allowances allocated. Compared to approximately 0.93 million tonnes of carbon dioxide emitted into the atmosphere, a deficit has therefore been recorded of approximately 0.77 million tonnes. The deficit was offset by the quotas purchased by the various companies, with an approximately cost of 57.4 million euros recognised in \u201cOther operating costs and expenses\u201d. There are no costs for Renovit (TEP), because the purchase of CO quotas is borne by the company to which the 2plant supplies energy net of the quotas in the hands of Renovit (TEP) for feeding electricity into the grid. These amounted to about 4,300 units, with a countervalue of about 0.3 million euros.The increase in purchased CO allowances is due to the increase in emissions resulting from the increase in gas 2consumption due to the increase in regasified, stored gas and to transport more natural gas from the South to the North of Italy.The increase in the number of CO allowances purchased and the increase in purchase prices led to higher costs than in the 2previous year<span class=\"_ _0\"></span>.",

Other unallocated amounts essentially relate to head office activities of Snam corporate and insurance captives.In order to assess the performance of the operating segments, Snam management mainly analyses adjusted EBITDA (net of any non-recurring costs or revenues, or costs or revenues resulting from events or transactions that are not representative of normal business activity) and adjusted EBIT<span class=\"_ _3\"></span>, for which a reconciliation with the related reported values is provided.In addition to the above measures, the Executive Board regularly analyses revenues and investments for each business.In order to allow for a better reconciliation with what is represented for management purposes, the representation of revenues has been modified, distinguishing \u201cRegulated revenues\u201d, relating to services subject to regulation by the ARER<span class=\"_ _4\"></span>A authority, from \u201c<span class=\"_ _0\"></span>Other revenues\u201d and \u201cOther income\u201d not subject to such regulation, instead of the distinction<span class=\"_ _0\"></span> between \u201cRevenues from ordinary operations\u201d and \u201cOther revenues and income\u201d. 41 <span class=\"_ _d\"> </span>Segment reported separately as a business subject to specific regulation, even if the materiality thresholds of IFRS 8 are not exceeded.

Members of the Board of Directors, Statutory Auditors and Key Managers, and their relatives and entities they control, including jointly with Snam, CDP and CDP Reti, are also regarded as related parties.As explained in detail below, related-party transactions mainly concern the exchange of goods and the provision of regulated services in the gas sector. T<span class=\"_ _0\"></span>ransactions<span class=\"_ _0\"></span> between Snam and related parties are part of ordinary business operations and are generally settled under market conditions, i.e. the conditions that would be applied between two independent parties. All the transactions carried out were in the interest of the companies of the Snam Group.Pursuant to the provisions of the relevant legislation, the Company has adopted internal guidelines to ensure that transactions carried out by Snam or its subsidiaries with related parties are transparent and correct in their substance and procedure.  Directors and statutory auditors declare potential interests that they have in relation to the Company and the Group every six months, and/or when changes in said interests occur; they also inform the Chief Executive Officer (or the Chair<span class=\"_ _0\"></span>, in the case of the Chief Executive Officer\u2019s interests), who in turn informs the other directors and the Board of Statutory Auditors, of individual transactions that the Company intends to carry out and in which they have an interest.Snam is not subject to any direction or coordination activities.

The Guarantee covers 80% of the amount of the Financing. The effectiveness of the Guarantee - pursuant to Article 15(9) of the Decree - is subject to the issuance of an ad hoc decree of the Ministry of Economy and Finance, in agreement with the Minister of Economic Development, adopted on the basis of the preliminary investigation submitted by SACE. Upon the issuance of the above-mentioned ministerial decree, Snam will be able to enter into long form financial documentation with the Banks, and Snam will subsequently be able to make the funding deriving from the Loan available to the Subsidiaries through intercompany loans, as provided for in the Decree, the Operating Manual and the General Conditions.The above transactions were processed pursuant to the \"Guideline on transactions involving the interests of the directors and statutory auditors and transactions with related parties\" adopted pursuant to Consob Regulation of 2010, Art. 4, which incorporates the amendments made by Consob with Resolution No. 21624/2020, and most recently amended effective September 14 2022.
